pepper, 3d plot of Spec in terms of Gaussian and Lorentz lw

[Sharon]

Dear experts,

I have a question. I want to simulate cw EPR and compare with my experiment result. To find the optimal linewidth, I want to simulate spec as a function of both Gaussian and Lorentz linewidth, but when I use two for loops to vary both linewidth, there was an error, says No broadening given, cannot compute spectrum with Exp.Harmonic=1. I am wondering if easyspin pepper cannot support to vary both linewidth?

Thanks

Sharon

The error you reported here might be because at some point in your double loop both line widths were zero. EasySpin needs a finite line width to calculate a derivative spectrum.
Anyhow, you might be better of in fitting the line width using esfit.

If you post a short script that generates the error, it will be easier to help you.
