@ZapperZ Yes, your input was very much needed and I agree, that is one thing that my input was lacking. The deconvolution process, although perhaps somewhat standard, is something that I myself have not previously encountered. (My career=I am now retired= was outside of academia and in the defense industry. My expertise is actually somewhat limited on this topic of Raman spectroscopy, although I do know the details of how a diffraction grating spectrometer works). ## \\ ## Additional item=I think perhaps only at most a handful of the Science Advisors and Homework Helpers on PF actually have any hands-on experience with Raman spectroscopy. I answered the question the best I could, having much familiarity with diffraction grating spectrometers, but my experience with Raman spectroscopy is very limited.That's fine, but the problem that I have here is that you've schooled the OP on the peak width from the spectrometer, but you didn't describe how the OP can go from that and extract out the instrument broadening from the data.
Note that the broadened peak may also be due to other factors (finite temperature of the experiment, etc.). From many of the Raman papers and talks that I've come across, one has to perform some form of a devoncolution to remove the instrument broadening. This, you never covered.
I've performed similar method in extracting the instrument resolution from ARPES data. So this is not an unknown or unfamiliar method.
