Mnova 14 has just been released this includes new features in most plugins: NMR, MS, NMRPredict, Screen, DB, Structure Elucidation, and also some new features.
We have added a new module, Mnova ElViS, for Electronic and Vibrational Spectroscopies, as we continue to add new analytical data that can be read, processed, archived and reported using Mnova. For those working on regulated markets and having to comply with 21 CFR Part 11 or GxP rules, Mnova 14 includes brand new Audit Trail and Digital signatures features
A recent paper in Journal of Cheminformatics describes An automated framework for NMR chemical shift calculations of small organic molecules DOI.
As an alternative, we introduce the in silico Chemical Library Engine (ISiCLE) NMR chemical shift module to accurately and automatically calculate NMR chemical shifts of small organic molecules through use of quantum chemical calculations. ISiCLE performs density functional theory (DFT)-based calculations for predicting chemical properties—specifically NMR chemical shifts in this manuscript—via the open source, high-performance computational chemistry software, NWChem.
Isicle is available from GitHub https://github.com/pnnl/isicle or can be installed using Conda (with required dependencies
conda create -n isicle -c bioconda -c openbabel -c rdkit -c ambermd python=3.6.1 openbabel rdkit ambertools snakemake numpy pandas yaml statsmodels
In addition, ensure the following third-party software is installed and added to your PATH:
ISiCLE is implemented using the Snakemake workflow management system, enabling scalability, portability, provenance, fault tolerance, and automatic job restarting. Snakemake provides a readable Python-based workflow definition language and execution environment that scales, without modification, from single-core workstations to compute clusters through as-available job queuing based on a task dependency graph.
There is more details on Snakemake here.
I've added Isicle to the Spectroscopy Page.
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:

There are more spectroscopy applications for Mac OSX 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,
