Erroneous results have been reported when using SpinDynamica v3.6.x with Mathematica version 13. This is very surprising behaviour since Mathematica should be backwards compatible. This has been pinned down to a surprising inconsistency in the handling of SparseArray objects between Mathematica versions 12 and 13. A bug report has been submitted to wolfram.com. SpinDynamica v3.7 …

Welcome to Christian Bengs who has taken over administration over this site. Christian has already done a lot of excellent coding as part of our new release of SpinDynamica (v3.0.1) and our first SpinDynamica publication. It’s great to have his help! So many thanks to Christian, and enjoy the new version of SpinDynamica! Malcolm

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. …

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.

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.
