Updates and Messages / SpinDynamica 3.0.1 released
« Last post by MalcolmHLevitt on August 21, 2017, 06:03:56 PM »
A substantial revision of SpinDynamica has been released as v3.0.1.
It may be downloaded from

Many thanks to Christian Bengs for a lot of help with the recoding and debugging of this new release. It would have been impossible without him. 

Hello Andy,
 I don't know the reason for this behaviour, but I find that it has solved itself in the new release SD3.0.1!
Dear Malcolm,

I am using:

SpinDynamica version 2.14.3

When trying to use PlotLabel *and* SpinDynamica, I get the following error:
The specified setting for the option FontSize cannot be used.

My regards,

Can that be modelled in the same way as chemical exchange? If yes, then just specify three instances of the entire spin system and set up the exchange process as described here:

Dear Ilya,

Is it possible to simulate the effect of Markovian jump dynamics on 2H MAS spectra in Spinach?
I would like to simultaneously fit a set of 2H MAS spectra, featuring jumping -CD3 groups, acquired at different temperatures to extract the static EFG tensor and jump rate constants, just as it used to be possible with Robert Vold's EXPRESS ( which, alas, is not available on-line anymore.
I'll be indebted.

Many thanks,

Thanks a ton.  I will check it out.   :) :) :)

sorry for the slow reply -- this has slipped between the cracks somehow. Yes, Spinach returns the optimal waveform. If you would like to run a gate optimisation, specify multiple initial states and multiple destination states as cell arrays.

It is possible, and examples that we did in collaboration with Dima Budker's group are already in the example set. See examples/nmr_zerofield folder.

I'm am super new to very low field/zero field NMR. I would like to be able to take NMR measurements from high fields and calculate zero field spectrum.  Is this possible with SPINACH?

The paper

J. Rantaharju and J. Vaara, Liquid-state paramagnetic relaxation from first principles, Physical Review A 94, 043413:1-10 (2016). []

uses SpinDynamica as a platform for the spin dynamics simulations.
