esfit results and simulation

Hello,

we are trying to use esfit to sumulate some rather complicated spectra of organic radicals. So far it works quite well, but when i use the the g-value, coupling constants and linebroadening provided by esfit and try simulate it, the simulation obtained does not look like the one esfit was showing as best result.

I have tried different methods, different scaling (scaling with baseline correction seem to work best, like lsq0). I have tried to use peak-to-peak linebroadening (lwpp) as well as FWHM (lw).

As far as I know the linebroadening is given in mT. I have tried if to convert them to Gauss, MHz and even tried if the value obtained is some sort of intrinsic value, where the starting parameter is set to 0 and the value retrieved is a fraction of +-1 of the range given.

Perhaps someone can help me with this issue.

Code: Select all

g = 2,006600879	
A1 = 10,67662615 G	
A2 = 3,412601787 G	
A3 = 3,411984069 G
A4 = 3,433421609 G	
A5 = 3,432924588 G	
lwpp = 0,232051906 mT
Seems like I can't attach the data converter get_MiniScope.m

Thank you all

One think to check for is to make sure your Exp.Range settings are the same for the fitting and the simulations.

Can you trim down your code to a small snipped that demonstrates the problem, without the experimental data?
