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)?

This is invaluable. Seriously. Thank you from Ohio State!

Excellent explanation 👌 👏

Please fix your title. Absorption

is it possible to get also the presentation slides please ?

Thank you for uploading this lecture! very useful and informative

Thanks very much, it is helpful！

Is it necessary to learn about the Fourier transform? Among them, to what extent should I understand complex numbers and Euler's formula?

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.

This helped me so much understanding the topic!

By ionize, do you mean excite?

WOW! Super informative. Thank you!

Awesome video, thanks!

Thanks a lot Sir, Highly helpful

Upload fitting tutorial videos please

It would be nice to upload a video on how to use different softwares relating to fitting.

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.

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.

Thank you for sharing, is this XAS facility open to public?

very informative and good explanations Thank you so much! guys! those who made this possible!

Very good explanation and more informative! Thank you guys for sharing with Us!

Great video. Thank you so much!

Very useful, thanks for sharing

Thanks for the talk. Helped me a lot.

Bravo. That helped me a lot.

Sir can you please upload about NEXAFS

Thanks a lot for uplouding this information, I'm working on my tesis and this information was too useful.
