All About ESR/EPR Spectroscopy 

I read many comments and got the confusion which you guys have, in that problem where we did for R3Ge radical why I didn't took Hydrogen attached to carbon and said it will not participate in splitting. Actually it should participate but here we have to neglect it for following reasons: Firstly it's not mentioned that what R is, is it methyl, ethyl, isopropyl what exactly R is, depending on that you have to take number of H. Since it's not mentioned so you cannot take any number of H here. Secondly in options you don't have any value more than 10 lines which is our answer after neglecting Hydrogens here, so you cannot have any other option to choose. Now if it would've mentioned in the question about R, then obviously we will take those Hydrogens in splitting. I hope it's clear now.

Thank you uploading in English cuz South Indians like us don't know hindi. But most of Indian utubers do video only on hindi. Thank you again

I think you belong to some other planet, thanks a lot sir, Brilliant way of teaching, hats-off

You are so good at explaining this. Thank you so much!

Thank you so much for the video! the best explanation i have come across

Thank you so much sir.till now I never couldn't see this much of explanation about ESR Spectra. Once again thank you sir 💐.

Thank you so much Sir. Your lectures are in a simple language, elaborative & crisp at the same time giving in depth concept, Very helpful & useful for MSc students like me, especially during this Pandemic time when I can't understand virtual college classes properly. Keep going.

After a long gap back with an excellent video thanq so much sir

Thankyu so much Sir..and missing you in RU-vid..your vedios are osm..plz..keep uploading..😊🙏😊👌

Thank you so much brother. I have waited a lot about ESR

Sir this lecture made my concept very clear bcoz of examples problm, thnku so much, u r the best😊👍👌

Thanks for the lecture sir. True respect from the bottom of my heart. I got some strength for preparing NET/GATE from this lecture.

Your classes are the best among all sir..keep uploading vedios..really helpful

the video on ESR and MOSSBAUER helps me a lot......thank you very much

Thank you sir Best explanation And u clear all dout related to physical chem... I follow your all videos Excellent work

An awesome way to revise the topic in last minutes thankyou 💛

Have been looking for dis for a long time....👍

Thank you sir. Really ur explanation is in a very simple way. I can understand it easily. Thank you so much

Very great sir u r doing a great job...we r thankful to u..

Yes, finally!! 🙌 Thank you sir.

nice explanation sir. i also have same doubt but Now Clear with comments. thank you so Much

Thank you so much sir for understanding the ESR topic in very easy and concise way. your teaching style is superb sir❤❤.

I am very much thankful to you Noorul Huda Sir and I really do hope that students will get benefit from your videos and it is beneficial for students like me who cannot afford coaching. Thanks for uploading your lectures and I personally request you please make more videos with more examples. Thanks a lot sir. Wish you all the best Sir.

Brilliant way of teaching.Thank you sir

Is Drago's rule applicable for coordination compound? Otherwise how hydrogen of Ammonia participate in splitting?

Thank you so much sir... Your way of explanation is very nice...

Wow, thank you so much. Much appreciated

Very nyccc..... brilliantly explained 👍

Thats a huge helpful video thanks

Thank you sir for nice explanation.I request you to kindly make a video on how to solve questions for the H2 atom like molecules dissociation energy,ionisation energy related problem..Frequently asked in gate (2016/2018)

Wonderful explanation. Very simple and easy way.

Thank you so much sir, wonderful one

Thank you so much Sir. You made more easy to understand this topic.

no doubt sir your videos are very helpful i secure JRF 87 in 2018 in which your videos play an important role now i prepare for UPSC geoscientist exam please help us with PYQ of geo scientist chemistry

Thank you sir.... Super explaination

Excellent!!! No words to say how amazing this vedio was.

Egarly waiting for this video :-)

After watching splitting of nh3 radical I tried to predict the spectra of cd2h radical which possess 10 lines but, I am unable to write splitting pattern. Can anyone help me? Thank u

Thanks a lot sir.

Thanku so much sir waiting for more such videos on youtube.keep uploading sir........

Your way of teaching is just perfect sir I had a query in question of germanium atom sould not we take two atoms of germanium although option of 19 is also not given but why is it so sir

Sir good evening.. U have one doubt, second example from last two Ge is there so why not we take in the formula of 2nI +1, the n value is 2

Thanks a lot sir.now it's very clear.you are great sir.plz upload some problems on mossbaour.plz

Tq u sir nice explanation sir.. Explain the kinetics of octahedral substitution(June 2017 booklet:A, q.no:31) pls explain sir and related questions

Tnq so much.,I understood clearly.. Please make more videos..tnq sir

Amazing sir tq u soo much i learned more from this vedio

In case if Ti(H2O)4(NH3)2 why didn't you take the 2 unpaired electron of Ti in the formula of 2nI+1 itself?

Thank you soooo much sir....

❤ really sir you are the best।।।।।।।।।no word ।।।।।

Great job!

Thank you Informative videos

Hope these youtube creators create all free content fully availbale for and specific for net chemistry

Tysm Sir!

Why you didnt take splitting of O in calculating htperfine lines in dragos rule in the Ti complex???please reply ASAP

Thanx sir..you r best..

Very useful ur video thank u so much

Thank you so much sir❤

hello sir u said that h connected to magnetically inactive atom like O,C are shows splitting then why u not consider h of alkyl group in the example of R3Ge question

Thanks a lot sir.....please upload video on inorganic NMR spectroscopy......

Good explanation. Thank u 💕 dear

Thanks a billion to u sir

You just nailed it :)

In ESR, while analysing ·OH radical using DMPO, I got ·OH signal and extra peaks. What could be the reason for excess peaks other than ·OH spectra?

which book you have to use in Dragos rule.. I have studied but can't find this rule.

Thank you so much sir!!!!

Very well done sir Sir can u gives video on features of esr like ligand hyperfine structure and fine Structure

Excellent sir

In anthracene 3 different hydrogens are present so overall 75 lines . And in phenanthrene 5 different hydrogens are present so overall 243 lines 🤗☺️☺️sir thank you much for the explanation 🤗it really helps me a lot . Respect and regards 🙏🙏🙏

Nice explanation sir.

Thank you Friend very much Hi from France 🇨🇵

Sir please make a video on Mossbauer spectroscopy just as like this...as possible as earlier sir ..it's humble request sir....and nice explanation sir

Appreciable❤️

Thanks a lot

Very2 ❤❤Thanks to you Sir understand easily Alhamdulillah

thank a ton....gr8 sir

If the I value is 3/2 what we have to take pascaline or non pascaline

Thank you sir

Thanks to you sir 👍👍

U r great sir

Sir. In( Mo(CN) 8)2- enriched with C13 gives how many lines? Here we have to take nitrogen in account. Please reply

Sir drago rule is only applicable for complex only right? It not for normal radical?

Super sir...thank you very much sir...

Sir your notes very good question also vry good

Sir u said that in CH2OH radical H attachef to O vl not take part in splitting hw u included it in CH2(OCH3)...sir plz xplain it i m getting cnfuse

Is drago's rule valid for complexes only?

Thank you so much sir

A good video. But I am comfused whether H in NH3 radical take part in splitting? how many number of lines will be obtained? In the last problem you discussed, 25 lines came out as answer but somewhere it has given 60 lines as answer, please explain.

Dragos law applies only for complexes Sir..??

Very much thanks please makes more videos

Thank u sir

why we count H in NH3 radical though N is magnetically active and in the later eg of complex we dont count H?

thanks sir

Sir can you please solve some questions about water exchange reaction...it'll help me alot

Superb sir

Very nice sir

Best video

super explanation

Superb👍👍 ♥️

Sir can u plz make a video related to natural product chemistry specially terpenes alkaloids and steroids...

Sir, is it possible that naphthalene radical contain 8 hydrogens, where will be the free radical place??.. could you please reply me sir..
