I have Raman spectra of carbonaceous materials from metasedimentary rocks and working on the estimation of their peak metamorphic temperatures. How can I deconvolute the spectra using the voigt function in Peakfit software for obtaining Raman peak values i.e. the G, D1, D2, D3 bands values as well as FWHM values; and other related parameters i.e. R1, R2? Suggestions and guidelines would be highly appreciated. Thank you.
Hi Nasir,
in my view, the best way is to follow the approach by Lünsdorf et al. (2017): https://doi.org/10.1111/ggr.12178
There is a protocol which you can follow step wise. Fitting is done by using IFORS, that enables to reduce the operator bias (Lünsdorf & Lünsdorf, 2016).
Best,
Jan
Dear Nasir,
I agree with Jan Schönig, try Lünsdorf's IFORS program, it truely works great. See Lünsdorf & Lünsdorf 2016 (Article Evaluating Raman spectra of carbonaceous matter by automated...
)you can find details under http://www.sediment.uni-goettingen.de/ --> Downloads.
Cheers,

Hi Nasir, Discuss your topic with Dr. Shahfaisal about this matter.
He will tell what to do.
The method is best described in Beyssac et al. 2002 (J. metamorphic Geol., 2002, 20, 859–871).
Dear Hafiz,
the deconvolution is not explained in this paper, except using a voigt function and the used software. So I recommend to use a reproducable fitting method like the IFORS mentioned. You can still apply the thermometer of Beyssac with the fitting results as well as other RSCM thermometers and compare the results.
Old thread, but...has anyone tried to use IFORS for soda lime glass?
Thanks!
