The latest release of SpinDynamica (2.14.3) is compatible with Mathematica 11. Lower versions are not compatible with Mathematica 11. See Downloads

The attached code may be used for simple 2D simulations using SpinDynamica. It is not completely general but should do for many purposes. More general code will be included in SpinDynamica in future. This example has also been posted on the forum, where you may also post responses.               …

SpinDynamica is used to treat the relaxation of long-lived singlet order in monodeuterated methyl groups and uses an effective CH2D geometry to explain experimentally observed results. Download the paper and the SpinDynamica notebook.

The new symbol PolarizationOperator may be used to calculate the polarization level of a spin ensemble and has been posted as an Add-On: http://www.spindynamica.soton.ac.uk/polarizationoperator/

On request, the popular Mathematica code CandRsymmetries has been resurrected as a new SpinDynamica add-on called SymmetryBasedRecouplingAnalysis. It may be found under AddOns or here.

SpinDynamica v2.14.2 has been released. See downloads  

Q & A with Malcolm Levitt on Wolfram Blog: here

In a recently accepted JACS paper, Russ Bowers and co-workers investigate parahydrogen reactions on nanoparticles, using 6-spin-1/2 SpinDynamica simulations. See: http://pubs.acs.org/doi/abs/10.1021/ja511476n

This example file illustrates the spin dynamics of a spin-3/2 system in the presence of weak and strong rf fields. Selective manipulations of the central and satellite transitions are illustrated, including the use of cosine-modulated fields to excite the satellite transitions.

The routine EnsembleAverage may be used to generate arbitrary distributions of nuclear spin interactions. In an example posted on the forum, I used EnsembleAverage to generate the spectrum of 133Cs (I=7/2) in an inhomogeneous gel. The same notebook includes a simulation of quadrupolar echoes in spin-7/2 with curious fractional timings.

At the present time, the case of spin systems experiencing chemical exchange cannot be handled entirely within the architecture of SpinDynamica. However, it is possible to build upon SpinDynamica to handle chemical exchange. I have posted an example file on the forum showing how to simulate an AB spin system of two spins-1/2 experiencing chemical …

SpinDynamica code for the interactive visualization of Euler angles is available here: EulerVisualization

A notebook for producing 3D animations of composite pulses is available here: https://www.dropbox.com/s/yam19kdjo8qtwva/CompositePulseAnimation.nb The plot shown is a single frame from one such animation.

DeVience, Walsworth and Rosen have used SpinDynamica to develop a new method for generating long-lived nuclear singlet order, and to plot the trajectories of the spin operators during the pulse sequence. See http://arxiv.org/abs/1307.0832

Andreas Brinkmann has used SpinDynamica to simulate 14N overtone NMR. See http://dx.doi.org/10.1063/1.4775592
