first i want to say thanks to the inventors of EasySpin, it's awesome!
Anyway, there is some additional information i'm interested in and i hope you can help.
I'd like to know if it is possible, to get the (double) integral of my best fit.
I'm using pepper to simulate S=1/2 spectra, with a wide spread(rhombic) g-Tensor.
In matlab one of the easiest ways to integrate your spectra(assuming the increment between points is constant which is the case with ES outputs) is to use cumsum a cumulative sum. Do it once for the integral, twice for the double integral.
Alternatively you could have pepper return the zeroth harmonic with the use of Exp.Harmonic = 0 and then integrate that using cumsum.
