It seems that you need to try fitting the fast regime using the garlic function, but this requires providing the full matrices of g and A.

The fitting range of esfit depends on the magnetic field range of the experimental data you imported and the Sys.Range variable you provided, not your plot range. If you want to customize the fitting range, you should manually change your experimental data range, pay attention to clipping sign inste...

Your spectrum has long tails on either side of the peak, so you should take Lorentz broadening into account instead of using a single Gaussian broadening. In addition, it is not recommended that you use the three broadening modes of lw, gStrain and HStrain at the same time, which will make your simu...

Hi DMWHZ, I am writing to share the results of my recent spectral analysis with you. I have successfully performed a precise fit to the spectrum, revealing the presence of three distinct components. Notably, each of these components exhibits a magnetic nucleus configuration: one with an I=1/2 nucleu...

Maybe you can try a slow motion simulation with anisotropic spin parameters. Here is a simplified example: clear,clf,clc; SysH.S = 1/2; SysH.g = [2.002 2.0029]; SysH.Nucs = '14N,14N,1H,1H,1H,1H,1H,1H,1H,1H'; SysH.A = [0.24 30;0.24 30;0.1 2;0.1 2;0.1 2;0.1 2;0.1 2;0.1 2;0.1 2;0.1 2]; % MHz SysH.lwpp ...
