At 29.33, the example that you took mam(pyrazine) contain 2 nitrogens also which are epr active so their contribution should also be there. Will there not be 25 lines? [2*4*(1/2)+1][2*2*1+1] (First part for Hs and 2nd for Nitrogen)
unlimited thanks mam....q ki ap free me padha rahi ho pehle badme apna coaching kholne wali ho q ki me coaching classes join nahi kar sakta isliye ....thanks a lot....
In H2 cation radical I think I is the nuclear spin. Splitting is due to interaction between electron spin and nuclear spin of proton ( Hyperfine splitting)
U r master in every topic....mozza aaa gaya....I hope if everything happens as I want then it is the 3rd topic which will be on the way...love and respect from assam
Thanks mam .... actually mujhe bhut khusi hui kyuki mai ishi ko pad raha tha aapka lacture dekha bhut help ....mam csir net ke har topic ki series vice video bnao ... bhut help ho jayegi..... thanks again
Thank you so much Jyoti. I am also a pass out of DU (2012-2014). I completed PhD and now studying for Gate. I have been away from the topics for a long time. But your videos have been it very easy for me. Very well explained and problm solving is the best part! Thanks a lot. Very helpful 👍
mam Why relaxation time ∆t is low in ESR or EPR, we can take this as high for sharp signal then we have no need for first derivative of I value... answer please 🙏
It's very helpful your channel in the period of lockdown I am going to watch your vedio one by one Starting from inorganic spectra Thank you madem🙏🌹🌹🌹🙏
In CD2H radical why did deuterium split the spectrum first and then subsequently H comes? Why can't it be the other way around? Won't the coupling of electron spin with a 1/2 species be greater than that with a 1 species?
Ma'am I've a doubt. In case of ethyl radical, you showed splitting for CH2 part first (1:2:1 -- 3 lines) then further splitted those 3 lines into 4 lines each due to the CH3 part In the last example of D2CH radical, u splitted D2 part first and then splitted those five lines further due to the H part. My doubt is - how to decide which part to split first ? Is there any rule for that or reverse also can be done?
In case of ethyl radical was with CH2 hence we always prefer the one having radical.... In second example radical carbon was attached to both the elements hence the one with high I value is preffered for splitting.
there is biggest confusion for me EPR part 1 ki vedio k 2nd last example me Nitrogen 'N' ki spin se hue splitting kyu nahi considered ki gayi jisme signals 5 arhe h agar N se splitting hoti to signal kuch or ate . Agar apne isliye considered ni ki kyuki N(15) ki natural abundance 0.37 hoti h to phir part 2 video k first question k 2nd no. NH2 hai jisme apne no. of line nikal ne k liye N ki bhi spin considered ki gayi h please help me out. and please reply fast..

Thanks a lot Mam for starting the inorganic Spectroscopy lecture series.
क्योंकी हमें इसकी जरुरत थी ,so please take this series in detail.
unlimited thanks mam....q ki ap free me padha rahi ho pehle badme apna coaching kholne wali ho q ki me coaching classes join nahi kar sakta isliye ....thanks a lot....
Very Informative and clearly explained by the Madam... Amazing .. Thank yuo!
Mam aapne to sach m chemistry m interest creat kra Dia😘 luv u mam
You are extremely talented and your way of teaching is amazing.

Thoroughly explained. Well done. 😘
:)
its very valuable im preparing for my semester exam from by watching your videos
Thanks mam ur videos are useful and also we have to write to less in notes..
Thanks a lot mam....ur way of teaching is awesome...
thank u so much mam😊 aap bahut asha pdate ho
In benzoquinone why haven't you take account of the oxygen in EPR splitting?
Thank you so much Jyoti. I am also a pass out of DU (2012-2014). I completed PhD and now studying for Gate. I have been away from the topics for a long time. But your videos have been it very easy for me. Very well explained and problm solving is the best part! Thanks a lot. Very helpful 👍
Giving GATE after phd?? Why
@@haryanvijatt2672 for PSU jobs!!
@@dibyasreechoudhury4287 apne assistant proff ke liye apply kiya h khi?
4:04 the molecular orbital for oxygen molecule is wrong... the lower set should be inverted
Yaaa it's a mistake, sigma 2p MO should be in lower energy due to absence of sp mixing.
Thanks mam.... loving your teaching style 💖
Thanks a lot ma'am for helping us ... I am watching it for my exam . Respect for you 💯.
Mam pyrazine m nitrogen ki spin b consider hogi....nitrogen ki wgah se bhi 5 line aayeghi aur total line 25 hogi ..
25 or 15 ?
Madam may be ethyl radical shows triplet of quartet not quartet of triplet.. Please madam check it...
Happy Teacher's day 💗
This lecture is very useful for me
Speechless 👏👏👏👏
Thank you so much ma'am
mam Why relaxation time ∆t is low in ESR or EPR, we can take this as high for sharp signal then we have no need for first derivative of I value...
answer please 🙏
You are good in epr.
It's very helpful your channel in the period of lockdown

Thank you madem🙏🌹🌹🌹🙏
sweet nd confident ESR details. Regards.
4:10 electronic configuration may change??
Parazide ke eg me nitrogen K liye b I include krke splinting lines ki value nikalenge so ans 25 lines ayega
Thank you so much ma'am ❤❤❤
Mam u teach really well thnkuu
My prediction says your channel is going to rise rapidly. Keep it up. You are doing a wonderful job.👍👍
Thanks a lot :)
You are correct
In CD2H radical why did deuterium split the spectrum first and then subsequently H comes? Why can't it be the other way around? Won't the coupling of electron spin with a 1/2 species be greater than that with a 1 species?
Can you please explain the esr for [Mo(CN)8]3-????
awesome just to say .try to upload some specific subject in physical chemistry for csir net
hii....tike suggestions drkr thila...mu quantum ra pura series dekhili..bht bhala thila..so sei comparison re spectroscopy ra series kemti achi?
Mam please do videos on mossbauer spectroscopy.....your teaching is very helpful.
In CDBr Cl radical, you said Br and Cl does not contribute to hyperfine splitting. Why? (Since Br and Cl have non-zero nuclear spin)
mam i liked your lecture quite a lot. but I think there is a mistake in the molecular diagram you have made of O2
mam plz follow to untold chemistry ....he is one of the best teacher...plz dont mind
Awesome way of teaching...
Very nice explanation great job
Mam ap ki writing bhut pyari hy
Thank you so much ☺️🌺
At time 29:45 in pyrazine actual no. Of line is 25, not 5.
Any book suggession please mam ?

Hello , I need your help to plot one spectra showing DMPO-OH adduct through ESR spectra. Please help.
Mam at a time 29.21 why you don't consider splitting due to nitrogen atom. Pls clear my doubt.
very useful video
Pyrazine radical anion vale example m nitrogen, electron se coupling nhi krta h kya
Your explanation is very nice$$
Mam your teaching style is superb. But try to provide correct data please.
Thank you mam, for a vivid explaination!!
Very nice teaching
superb concept di
Kindly upload videos on omc for csir net exam..
The important topics that need to be covered in this topics plz..
I will :)
Thanks madam, you explain well, keep it up.
Why is the contribution of CH2 greater than that of CH3 in ethyl radical?
It is really so helpful.
very helpful and excellent explained
Mam please next video on English version
Great teaching
Thanks :)
Nice explanation mam.. 👌😊
Superb ma'am very useful trick...
Very helpful video thank u so much mam
Wonderful teacher 👏👏👏
Kind request wonderful teaching plz videos in english
Ma'am for O2 spin filling order more than 14 electron not applicable here why ?(for O2 it is 16)
Ma'am I've a doubt.
In case of ethyl radical, you showed splitting for CH2 part first (1:2:1 -- 3 lines) then further splitted those 3 lines into 4 lines each due to the CH3 part
In the last example of D2CH radical, u splitted D2 part first and then splitted those five lines further due to the H part.

In case of ethyl radical was with CH2 hence we always prefer the one having radical....
In second example radical carbon was attached to both the elements hence the one with high I value is preffered for splitting.
Mam, 30:29 pe 2 nitrogen atom is also present .will nitrogen not taking part in the spliting of esr ?
Yes they will take part and ans will be 25

Thanks mam. Your contents are awesome
Thank you ma'am
Thank you so much mam for making this video 🙏🙏🙏🙏
Mam, please do the classes in English
Esr derivative are generally recorded in first derivative mode not in the absoption mode why???
Excellent... Madam...
Thanks :)
