Deconvolution (multiple peak fitting) of raman and photoluminescence spectra using fityk

In this short tutorial, learn how to fit multiple Raman or photoluminescence spectra peaks (deconvolution) using Fityk software. The FitYk software can be used to fit a variety of peak shapes, including Gaussian, Lorentzian, and Voigt peaks. This makes it a versatile tool for analyzing data from various sources, including spectroscopy, chromatography, and microscopy.

Hello!
Thank you. I did not know about this software. I have used Origin software to deconvoluted but is difficult do it.
I have some question.
What are the most important parameters to be taken care of in order to deconvolute?
How important is it to maintain the same curve width in each of the components that adjust the envelope?
Could you suggest any bibliography that could help me with deconvolution of Raman spectroscopy?

Thank you so much for the video, it was amazing. I would like to know if you have some references about fitting Raman spectra with the Voigt function. I always do this with Lorentzian functions.

I am a maths enthusiast, i wanted to know the mathematical theory behind it and specially if i wanted to do the reverse case (i.e. If i have multiple peaks and i want to merge them into one) how can i do it, and any mathematical reference behind it. Thank you.

Thanks for the video. I hope you upload always. We would love to see Rietveld Refinment in GSAS software.. thank you Sir!

Your fit's WSSR value is 179. Good fit should have the WSSr value close to 1 right?

Thank you so much sir for this tutorial

Thank you for the tutorial. It is very helpful. However, I have some trouble with importing XRD Data into Fityk. I could successfully import my .njc data of 2-Theta and Intensity into Excel (.xls) file. Could you tell me to which file format should I need to convert my .xls file to be able to import into Fityk?

Thank you for this tutorial. Is there an alternative to download to replace origin?
