Title: Resolution FT-Raman spectrometer
Post by: -SERS- on August 14, 2012, 05:50:13 AM

I've just started doing a project with a rather old FT-Raman. I'm wanting to determine if there is a change in crystallinity in apatite upon subjection to certain conditions; I do this by monitoring phosphate's intense symmetric stretch and fit mixed Lorentzian-Gaussian curves to them in GRAMS. If the resolution used is 1 cm^-1, is the smallest I can quote the wavenumbers ±0.5 cm^-1? Or is it permissible to quote the wavenumbers to even lower since I'm using a Lorentzian model?
