Insensitive (Incredible Nuclear Spin EvolutioN Simulation Tool Intended for Visual Education) is an application to simulate the NMR experiment based on the quantum mechanical density matrix formalism.
It is available for Mac OS X 10.6 and above and iOS 5.1.1 and above. Full details can be found in Concepts In Magnetic Resonance, 2011, 38A (2), 17-24 DOI.
The NMR experiment is usually described by a choice of three models that operate on different levels of abstraction: the vector model, the product operator formalism and the density matrix approach. The transition between these models poses a didactic challenge for teacher and student alike. A new computer program is presented, which simulates a spin system on the textbook level and compares the three approaches, with the possibility to manipulate the system at every step. It closes a gap between NMR education and professional simulation tools. Some algorithms are explained, which are used in the simulation to extract information from the density matrix.

I just noticed this mentioned on Twitter and so I've added it to the Mobile Science site.
NMR Solvent peaks is a conveniently-searchable version of the ungainly table of NMR data most organic chemists keep a copy of nearby. Instead of searching through the table for a peak near your unidentified peak, just enter your solvent and the peak's multiplicity and location and you'll have a short list of candidate impurities
There are a number of other NMR apps available
A discussion on the new developments of Xplor-NIH DOI. Xplor-NIH is a popular software package for biomolecular structure determination from nuclear magnetic resonance (NMR) and other data sources.
Most of Xplor-NIH's code is now being developed directly in the Python language, and thus is directly accessible for modification by the end-user without recompilation, while code paths which require high performance, such as those executed at every timestep of molecular dynamics, are coded in C++. The Python interface to Xplor-NIH provides an extensible toolbox for developing further functionality. Precompiled packages for most popular Unix and Unix-like operating systems (such as Linux and Mac OS X), as well as documentation and support are available directly from http://nmr.cit.nih.gov/xplor-nih/.
I just came across a publication DOI describing ARIA2 (Ambiguous Restraints for Iterative Assignment) is a software for automated NOE assignment and NMR structure calculation.
ARIA comes as a software library written in the object-oriented programming language Python. The modular design makes it easy for the user to extend and modify the program. The GUI is based on the graphics libraries Tcl/Tk and Tix, interfaced by Python.
ARIA runs on Linux, SGI machines and Mac OS X.
More details can be found on the website http://aria.pasteur.fr.
I've added ARIA2 to the spectroscopy page.

The latest update to iNMR version 6.0.0 is available for testing.
Version 6.0.0 requires Mac OS X El Capitan. Today only 60% of Mac users have it. This doesn’t seem the right moment for replacing version 5. In conclusion, version 6 is currently available for a few selected testers only. Anybody can apply. Testers will receive a key that is going to expire in December. The keys for version 5 are not valid for version 6.
iNMR is a high performance NMR analysis program.

The very popular NMR processing tool iNMR has been updated
The new versions 5.3.7 (for Mac) and 2.3.7 (for Windows), both available since June 20, add Covariance NMR to the processing toolbox. This technique creates a symmetric square matrix, starting from any 2-D matrix. The result can look completely different from the starting spectrum, though the information contained is necessarily the same. An example is hsqc-tocy (a kind of hetero-correlation experiment). After normal processing, it has two different axes: a 1-H axis and a 13-C axes. Starting from here you can apply two different kinds of Covariance. The so-called Direct Covariance creates a symmetric H-H matrix. The so-called Indirect Covariance creates a symmetric C-C matrix. Both are homo-correlation plots.
A more detailed description is available here:

The very popular NMR application iNMR was updated recently to version 5.3.6. This is a minor update:
When the slider for the first-order phase correction reaches the end-of-the-run, a message appears at the center of the same dialog: "Move This!", meaning that, if you want to go further, it's enough to touch the "fine-coarse" selector.
I’ve updated the spectroscopy page to reflect this
rNMR is an add-on for R.
rNMR is an open source software package for visualizing and interpreting one and two dimensional NMR data. In contrast to most existing 2D NMR software, rNMR is specifically designed for high-throughput assignment and quantification of small molecules. As a result, rNMR supports extensive batch manipulation of plotting parameters and has numerous tools for expediting repetitive resonance assignment and quantification tasks.
I’ve added it to the spectroscopy page.
Learn NMR FID is a great teaching tool to learn the basics of NMR data collection and processing. Use simulated free induction decays (FIDs) and spectra to see apodization, noise and relaxation effects. Move peaks and see how the FID changes. Real and imaginary FIDs prior to and after processing are displayed as is the resultant spectrum after the Fourier transform.
There are more science apps for iOS on the mobilescience site.
I also thought I’d mention this framework that was brought to my attention recently. There is a trend to move massively parallel tasks to the GPU, GPU Image is a framework (BSD license) that simplifies the creation of GPU filters. This framework is built around OpenGL ES 2.0, so it will only work on devices that support this API. This means that this framework will not work on the original iPhone, iPhone 3G, and 1st and 2nd generation iPod touches. All other iOS devices are supported.
Accept-NMR uses an input PDB file, generate symmetry-related copies of a biological molecule of interest, and predict specific user-defined classes of intermolecular contacts between these (using a user-defined distance cutoff). Sort and analyze the resulting contacts, and visualize the results using several visualization schemes in PyMOL. Predict NMR spectra, and specifically the positions of intermolecular contact cross-peaks, based on the contacts predicted and chemical shift table. It is written in Perl, utilizing Gtk2-Perl bindings to provide a cross-platform compatible graphical user interface,
Added to the Spectroscopy page.

I noticed this in the iNMR newsletter.
FREE FOR EVERYBODY Only today 22nd Feb, anybody can ask for a free key for iNMR reader 5. No questions asked. iNMR reader 5 is a 64-bit application that requires Snow Leopard (or a later OS).
A new iNMR reader is available after many months. Instead of restarting from the old version, I have started from the full edition(which includes CPM, DOSY, relaxation times and many other things missing in the old reader), from which I have removed just three commands: Save, Export and Console. In practice it's the iNMR you have appreciated in the past year at a much lower price. Another thing that changes is the key: the old key isn't good. If you already have a license, please wait until March to install this new version and ask for the key. There is no upgrade fee to pay, but remember that a disposable license can't be moved to another computer. You will receive the key valid for your old computer. To ask for a new key, please send the old one back.
The Collaborative Computing Project for NMR was updated last night. No details are available.
The Collaborative Computing Project for NMR (CCPN) is a project that aims to bring together computational aspects of the scientific community involved in NMR spectroscopy of biological molecules, especially those who work in the field of protein NMR. The CcpNmr software suite is a series of programs for macromolecular NMR spectroscopy integrated with the CCP data model. Between programs written by the CCPN, external contributions, and ‘outside’ programs integrated with the data model, it is the intention to provide one suite of programs to carry out all tasks needed in macromolecular NMR spectroscopy. The nature of the data model guarantees that any other program or suite that interfaces with the data model can be used alongside or instead of the CcpNmr suite.
CCPN will be giving a demonstration at the EUROMAR conference during the first week of July (see http://www.euromar.org/). They will also be handing out CDs with the latest release.
There is a page of spectroscopy applications for Mac OS X here.
The latest Mac version of iNMR is 5.2.4, released today. Due to popular demand it restores the slider for zero-order phase correction, which reappears side-by-side with the knob that has been in its place for a whole year. Their function is equivalent. This seems to be a case where it's better to have redundant controls.
Just got this message I thought I’d pass on.
The iNMR reader will remain at €39 for another 5 days only. Staring from Tuesday, it will return to its old (historical) price of € 50. The same applies for the student promo and the laptop extensions, everything that now costs €39 will cost €50 starting from next Tuesday.
iNMR is the only NMR software expressly written for Mac OS X, it uses Mac technologies and is tightly integrated with Mac OS X.
There is a listing of spectroscopy applications here.
After many months of beta testing the latest version of the popular Mac dedicated NMR spectroscopy application iNMR5 has been released. The key new features are tabulated below.
- Version 5 requires a 64-bit Intel chip and Snow Leopard. Version 4 is 32-bit Universal Binary and requires Tiger.
- real-time dragging
- When you drag the margins of the plot, or the integrals, or most of the objects, the plot is continuously updated. Overlay manager
- The Overlay Manager becomes non-modal and can be enlarged to show the full path of the individual documents. Sorting the overlays is simpler and more transparent.
- Manual phase correction
- The zero-order correction is controlled by a knob that never reaches the end of the run. The fine-coarse selector has many more stops. The phase panel is more compact.
- Other dialogs
- “Units and Scales” and “Colors and Levels” change the corresponding plots as soon as you click into a control. The Preferences dialog includes a “Preview” button. The color panel is no more modal. When the open dialog is open, the corresponding menu item isn't dimmed anymore. The console is more compact than in the past, but can be enlarged at will.
- Fit to overlay
- Fitting a simulated spin system is visibly faster.
- The new cursors are more specific. The horizontal palette has a single row of buttons.
- Info tool
- The interpolator is faster, more predictable and more reliable.
- The visual effect of the command ”New Page” is realistic.
- The printed area is no more centered and no more clipped.
- Shows an estimate of the T1.
Depending on your existing license you may be eligible for a free upgrade, for other users there is a small upgrade fee.
