How to do Multiple Peaks Fitting | Origin | XPS, Raman, PL spectroscopy │Curve Fitting

This tutorial video explains how to do #MultiplePeakFitting using #Origin #PeakAndBaseline tool. This video shows multiple peak fitting of #RamanSpectroscopy data. But, this process can equally be applied for multiple peak fitting of photoluminescence (PL), XPS etc. without very deep understanding.
In a previous video by "Easy Way How To", the basic multiple peak fitting in Originpro 8.5 was shared on KZbin ( • Multiple Peaks Fitting... . It has become very popular among researchers. Some of the viewers have asked for a similar video with explanations. They have also asked several questions. Hence, with their suggestions, we are sharing this tutorial with explanations and answers to their questions.

Thank you for the explanation. It's very helpful.

[@m.s.b.8929]

Thank you so much for this. Awesome!

[@leshanusgodaarachchi9699]

Nice explanation. Thank you!!

[@InSciLab]

You are welcome!

I have to find ratio of D/G bands....after fitting peaks like the way you have shown, how it should be calculated .....

[@esraaahmed9314]

Hi can I ask about how you identified the spectrum itself (TO2, TO3, etc .......)

[@Zulqarnainhaiderkhan]

Amazing. This video is really helping. You explained it very well and in a very easy way. I'm using Origin Pro8 but unfortunately, Origin Pro8 doesn't have Voigt to fill multiple peaks. Could you please help me how to fit multiple peaks for Voigt using OriginPro8? Thank you in advance.

Doesn't matter. Don't bother. Think about the peaks scientifically. What it can be at best. Use that. You can read the related articles on our site. Search "InSciLab" on Google or any other search.

Please explain how to identified A1, E1... peaks. Is there any selection rule?

How can I combine the graphics for the band gap in one drawing if the values ​​are different and the x- and y-axes are not equal?

[@prakashbinnal7884]

Dear sir, I need to evaluate the D to G band ratio....should I do peak fitting or directly go for area under curve ? I have just started with learning Raman spectra

[@InSciLab]

Doing individually and then taking ratio would be appropriate, if I understand your aim correctly.

hello I am using origin 2016 and in the multiple peak fitting dialougue there is no box of " number of peaks" can u please help. I tried taging the peaks but it is not working too

[@InSciLab]

watch first part of this video kzbin.info/www/bejne/n6indIiHZdVrgLM

[@dhananjaydoke6237]

how you took baseline? Sometimes when we do it peaks goes below baseline can you explain that
