Wow, that was very helpful. Just started to explore the topic, and this lecture cleared a lot of fog. Massive thanks for putting this on TH-cam and keeping it here, accessible to everyone.
I think the guy who asked about the spectra beyond absorption edge is probably asking how and why the spectra evolves as the energy scale is getting higher. XAS (gausian)and XAFS is slightly different in that respect, I think this is his question. My perspective: After the edge jump there is no major energy that is absorbed by the sample. Post edge the absorption feature gets slowly towards lower y axis value. The extra energy beyond edge allows different complex phenomena to happen so we see a different feature. It is best understood in inverse position. Give it a thought. Or read Bunker book.
Firstly, hearty thanks for the wonderful informative video. I am a Chemical Engineer and my research is in catalysis. Much of the chemistry and other stuff discussed require an explanation. So can you make a video for beginners, for people outside the basic science background? Also, a detailed video on NEXAFS and EXAFS along with the interpretation of the spectra would be of greater help. Thanks and looking forward to the requested content.

Thanks a lot for uplouding this information, I'm working on my tesis and this information was too useful.
This is invaluable. Seriously. Thank you from Ohio State!
Very good explanation and more informative! Thank you guys for sharing with Us!
Thank you for uploading this lecture! very useful and informative
This helped me so much understanding the topic!
WOW! Super informative. Thank you!
Excellent explanation 👌 👏
Thanks a lot Sir, Highly helpful
Thanks for the talk. Helped me a lot.

Based on XANES experiments, what is the timescale for reducing metal ions (+X; where X could be 1, 2, 3, or more) to metal atoms (+0 oxidation state)?
Bravo. That helped me a lot.
Thank you for sharing, is this XAS facility open to public?
Very useful, thanks for sharing
is it possible to get also the presentation slides please ?
By ionize, do you mean excite?
No, he means ionize
Sir can you please upload about NEXAFS
Please fix your title. Absorption
