My version of Origin only shows the width. It does show the formula that relates width to FWHM in the "Sample Curve" box at the bottom, but how do I add FWHM directly to the list of parameters?
Do we need to reduce Chi square further? As in your video, it comes out around 445. So, is this fit okay for getting the FWHM value, or do we need to bring down Chi square close to 1?
Dear Phys Whiz, In your amazing video explained about Gaussian-Gaussian fitting. But how about Cauchy-Gaussian fitting? I tried in Origin and CrystalSleuth software but it cannot. Do you know another software to do Cauchy-Gaussian fitting? Best regards
hello there, how can I calculate the dislocation density of a specific deformed steel using this software? My doubt is because i've seen that there's a possibility to determine by XRD. Then I would appreciate if you share with us your knowledge concern that. Thank you.
Thiago marques ivaniski it might be too late but you can calculate the dislocation density by the formula d=1/D^2. Where D is crystalline size and d is dislocation density.
The FWHM you get from the Origin is in degrees. To get the crystallite size, or to use the Scherrer's Formula, FWHM needs to be converted to radians. Hope that clears up the confusion.
It was a very useful video. After we get cos theta, do we have to convert it into radians and then substitute the value in radians in the Scherrer's formula and use it to calculate crystal size?
Theta is the diffraction angle. In the diffractogram, you have 2theta in degrees on the x-axis. So just divide by 2 and then find the cosine of that. The FWHM returned by the software is in degrees too. Using that and the value of cos theta and K, you can find out the crystallite size L
thank you so muuuch! You saved my thesis
It is very useful, sincere thanks. I intend to watch and learn from your videos. Have subscribed as well.

Pls explain the xrd data, to strain dislocation density
Thank you very much for this video.....Really very helpful

Which peak is fit that peaks only we take for analysis of crystallite size ah sir
How go back original graph after fit peaks?
Are crystallite size and grain size the same?
How to find the corresponding intensity value of xc value.? Thanks in advance.
Thank you so much! This was wonderful!

Is the FWHM data given by origin in degrees or radians?
sir how to calculate lattice parameter of composite film with different concentrations of doping
Cúal es la interpretación de chi-reducido en este fit?
Thank you so much! it is very perspicuous =))

i can't fit until converged, the red line didn't suite to the grafic. it only became straight line. please your help tq
very well explained
Sir to find crystallite size we convert FWHM in radians but what about theta? doest it also need to convert in radians?
yes. theta also should be converted in radians
@@KAMALAN1984 we should convert fwhm (2theta) to theta to radians
Or keep as it ?
can you tell me about the version of the software?
How to get 2 théta and intensity ?
Thank you
Does it give FWHM value in radians or degrees?
Degrees. You will then need to convert it into radians.
Manas Sharma Thanks.
FWHM value in 2theta (degrees)?
The FWHM you get from the Origin is in degrees. To get the crystallite size, or to use the Scherrer's Formula, FWHM needs to be converted to radians.
Hope that clears up the confusion.

Thanks, that was useful
nice work
thanks man
cant use this for origin 8 :(( sad
me too. maybe phys whiz can explain this and reply the comment.
@@masulum.channel i upgraded to origin 2018, and this is ok
@@darkblader061 I already have origin 2018 but I don't have the fit peaks
Write the handwriting explain
how to get cos theta ? is cos theta is equal to FWHM?

well i already got my ressult, i relize that already, and i feel stupid to asking you that question haha.
No worries. Happens to the best of us. :)
anyway i have more question, how we analyze the crystal structure (111) (102) (100) etc, can i using MAUD software to do it?
what the use of L
hello, I can't calculate FWHM with Origin8 Thank you
rafika djebien I also couldn't calculate
