Calculating FWHM for XRD Peaks using ORIGIN

A detailed explanation of how to calculate the Full Width At Half Maximum(FWHM) for the peaks in the XRD pattern.
The video demonstrates the use of Origin to perform a Gaussian fit of the XRD data to get the FWHM.

thank you so muuuch! You saved my thesis

[delphinj]

Pls explain the xrd data, to strain dislocation density

[HuggumsMcgehee]

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?

[abhijeetdas]

Are crystallite size and grain size the same?

[sonalchemy]

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?

Cúal es la interpretación de chi-reducido en este fit?

[mdraufulkarimkhan]

Thank you very much for this very helpful

[michaelviti]

Thank you so much! This was wonderful!

[Ifti]

can you tell me about the version of the software?

[rafikadjebien]

hello, I can't calculate FWHM with Origin8 Thank you

[huytrinh]

Thank you so much! it is very perspicuous =))

[thiagomarquesivanisk]

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.

how to get cos theta ? is cos theta is equal to FWHM?

[sudeshhk]

How go back original graph after fit peaks?

[vijayendragarg]

It is very useful, sincere thanks. I intend to watch and learn from your videos. Have subscribed as well.

[sagarrawal]

How to find the corresponding intensity value of xc value.? Thanks in advance.

[faheemwani]

sir how to calculate lattice parameter of composite film with different concentrations of doping

[varshinipreethi]

Which peak is fit that peaks only we take for analysis of crystallite size ah sir

[ichbinangie]

Is the FWHM data given by origin in degrees or radians?

[vinaagustinagultom]

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
