Electron paramagnetic resonance (EPR) sometimes also known as electron spin resonance (ESR) spectroscopy is a very sensitive and powerful analytical tool used for the detection of different oxidation states and the chemical environment of an atom. It also tells the atom has either tetrahedral or octahedral coordination. It works on the well-known quantum mechanics principle Zeeman Effect. In this tutorial, I have shown how to calculate the g-factor from the EPR spectroscopy parameter that can be calculated from the data.

Okay this was actually a great help, not just because of the EPR, but mainly because I can't navigate the Origin UI to save my life
Thank you sir! You just saved my life
Thank you so much! This is so helpful and clear.
i got value of g factro 2.2 and 2.4 in tio2 rutile but litracture shows its lower than that how its possible
Thank you for such an informative video
My pleasure
Thank you so much.how to know g parallel and g perpendicular in this spectra? Can you explain?
can you show how to deal with Mn2+ and Mn4+ in detail？thank you
Pl make a video for VSM, XPS and UPS data.
I have a question on plotting intensity vs g factor bc we know that g factor depends on resonance field only why do you take all the B values of the spectra instead resonance field
Dear lecture,
I would ask a question about g-factor. At this video time laps 8:00-8:32 you did type function and programme give some numeric. I did make the same this yet, origin 6.0 programme did not come out the numerics. Can you give me a hand? Wşth my best regards.
Thank you so much!
Nice one. Very useful! Thanks
Glad it was helpful!
thank you so much sir, this is very help full for us
but to know the oxygen vacancy is create or not
Nano world 🙋🏽♂️
if we have magnetic field in Gauss then how to convert into mT or we can plot graph in same way in Gauss
Thanks for your video, How to get g parallel and g perpendicular values from the spectra?
Please help me with a video related assymetry dysonian lineshape equation fitting for EPR data
I saw it very well. Do you have any tips to tell if it is unpaired electron or impurity in comparing sample data and reference data?
How to know the saturation magnetization of the material before performing EPR experiment?
Thanks a lot☺️👍👍
Most welcome 😊
Thank you
thank you
Thanks,... how to calculate average of total amplitude?
Thanks nanoworld, I hv one question..
What we conclude from two peaks, 6 peaks or multiple peaks in esr spectra??
Do you have any video, how calculate hypfiner A?
Can you plz help me out. There is straight line along horizontal I from of 0 point of y-axis with my ESR data. How can I remove this line
I have checked and resolved this problem by the data sent by one of our followers.
His data was taken in the magnetic field range of 284 mT to 374 mT. There were 1000 data points in this range. But I have noticed after 1000 points of data (at 374 mT), his data start again from the beginning (284 mT). This means he was plotting his data twice. The endpoint of the first data was connected with the starting point of the second-time data. That's why a straight line appears in the graph. This problem occurs because the actual format of the data was .json and the file was improperly converted to another .txt format.
*Solution:*
I copy-paste the first 1000 points and then plot them, his problem was resolve. I did this with the file sent by him and his problem was resolved. If you are still facing a problem, please contact me at fascinatingnanoworld@gamil.com
Thank you
@@nanoworld6122 thankyou so much. It was really helpful.
Thank you!
Welcome!
Thank you for informative video. I have one question, how to get EPR deconvolution ? (the asymetric EPR data)
Thank you
You're welcome
