ESEEM simulation for high-spin compounds

Hello,
This is my first trial to simulate ESEEM spectra of Mn(II) compounds, and I want to confirm the code for "saffron for high-spin compounds".
Especially, when CW-EPR of Mn(II) using pepper, the zfs parameters(D, E) are needed & added in the code. Similarly, I wonder about the case for ESEEM.

1. Do I make the code with zfs parameters in 'saffron' (ESEEM simulation)?
2. If the following code is incomplete, could you kindly give advice for the code?

Code: Select all

Exp.Sequence = '3pESEEM';
Exp.nPoints = 256;
Exp.dt = 16*0.001;
Exp.T = 80*0.001;
Exp.mwFreq = 9.7;
Exp.Field = 3370*0.1;
Exp.tau = 210*0.001;
Exp.ExciteWidth = 1000/16;

Sys.S=5/2;
Sys.Nucs = '14N';
Sys.g = 1.9999;
Sys.A = 0.2+[-0.1 -0.1 +0.2];
Sys.Q = [3 0.1];

[time, signal]=saffron(Sys,Exp);
Thank you in advance for your effort and time.

You need to add the ZFS in Sys.D.

I really appreciate your answer. Could I make complete the code with only ZFS parameter(Sys.D) without any information for specific nucleus? (for this case, 55Mn)

For Mn(II), the hyperfine coupling is usually large, so you might have to include it, in addition to the zfs.
