Difference between V6.0.0 and V5.2.35

Hi everyone,

I met a significant difference in generating an EPR signal using V6.0.0 and V5.2.35, especially for parallel mode signals. So I checked the roadmap, and both the signals arose from the transition between S=-2 and S=+2. The difference is that the resonance field changes rapidly in V6.0.0 but slowly in V5.2.35. So which one is more robust?

here are the code and the generated signals.

cm = 29979.2458; %(1con = 1cm-1 = 29979.2458MHz)
D = -6;E = D * 0.122
Sys0.D = [D E]cm;Sys0.S = 2;Sys0.g = [2.0 2];Sys0.lw = [0 16]; Sys0.DStrain = [1 0.06]cm;
Exp.Range = [1 701];Exp.Temperature = 10;Exp.Harmonic = 1;
Exp.mwFreq = 9.627327;Exp.Mode = 'perpendicular';
Opt.GridSize = 31; Opt.Threshold = 0;
[B,spc3] = pepper(Sys0,Exp,Opt);
Exp.mwFreq = 9.398139;Exp.Mode = 'parallel';
[B,spc4] = pepper(Sys0,Exp,Opt);
plot(B,spc3,'r',B, spc4,'b'); axis tight;

fitting spectrums also met this difference.

To get parallel mode in version 6, use Exp.mwMode instead of Exp.Mode.
