Origin Version (Select Help-->About Origin): 7.5
Operating System: WinXP
In electron spin resonance spectra, the experiment gives the 1st derivative signal.Using the derivative of the Lorentzian function
 ,
where the dependence variable is P and the independence variable H,
I want to fit the signal and don't know how to treat.
Firstly I transform the experiment signal into integrated curve, then fit with Lorentzian function, but I always think that the results are dependent with the baseline.
I saw the similar question in Tip of the Week, which is Fitting with Integrals, so I think it can be done with Origin, and I want to know detailed process.
