I usually use Python (scipy, lmfit), but so far it didn't really work, as there are many peaks in one spectrum, so many parameters to fit for and I think that the fit gets stuck in a local minima, before reaching the actual parameters (but if you know a python package good enough for what I need, I am willing to try).

I have some data from a molecular spectroscopy experiment, containing vibrational and rotational spectra, and I want to fit the peaks with Voigt profiles (one for each peak) in order to obtain the centers of the peaks. WinPLOTR includes automatic and manual peak finding, peak profiling, and passing the results onto several indexing programs.
