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....
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
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)
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)
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 👍
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?
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 🙏
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.
Thanks a lot Mam for starting the inorganic Spectroscopy lecture series.
क्योंकी हमें इसकी जरुरत थी ,so please take this series in detail.

Thanks mam.... loving your teaching style 💖
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.
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)
its very valuable im preparing for my semester exam from by watching your videos
thank u so much mam😊 aap bahut asha pdate ho
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.

Thanks mam ur videos are useful and also we have to write to less in notes..
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
Thanks a lot ma'am for helping us ... I am watching it for my exam . Respect for you 💯.

Starting from inorganic spectra
Thank you madem🙏🌹🌹🌹🙏
Happy Teacher's day 💗
Thank you so much ma'am ❤❤❤
Very nice explanation great job
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 ?
superb concept di
4:10 electronic configuration may change??
Nice explanation mam.. 👌😊
In benzoquinone why haven't you take account of the oxygen in EPR splitting?
Awesome way of teaching...
This lecture is very useful for me
Mam u teach really well thnkuu
You are good in epr.
At time 29:45 in pyrazine actual no. Of line is 25, not 5.
Wonderful teacher 👏👏👏
Your explanation is very nice$$
very helpful and excellent explained
Thankyou di ❤😊
very useful video
Thank you mam, for a vivid explaination!!
Excellent... Madam...
Thanks :)
Very nice teaching
Very helpful video thank u so much mam
Great teaching
Thanks :)
Superb ma'am very useful trick...
It is really so helpful.
Thanks madam, you explain well, keep it up.
U r just superb😎😍😍
Hello , I need your help to plot one spectra showing DMPO-OH adduct through ESR spectra. Please help.
Thank you so much mam for making this video 🙏🙏🙏🙏
Congratulations Mam on 100K Subscribers 💯
Mam ap ki writing bhut pyari hy
Thank you so much ☺️🌺
Pyrazine radical anion vale example m nitrogen, electron se coupling nhi krta h kya
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
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?
Nice explanation..supb mam
Thanks mam. Your contents are awesome
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 🙏
Can someone pls explain why carbon 12 divided by 4 to know its spin? @ 15:18
Mass number completely divisible by 4 gives nuclear spin 0.
Wel done Miss
Can you please explain the esr for [Mo(CN)8]3-????
🌹🌹Thank u mam🙏🙏🙏🙏
Superb mam
Awesome!!
No words to say thanks
Mam keep it up
N plz make vedio a/c to csir syllabus topics lectures then their question solutions☺☺☺
Mam please do videos on mossbauer spectroscopy.....your teaching is very helpful.
Thank you so much mam...
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 plz follow to untold chemistry ....he is one of the best teacher...plz dont mind
How to explain the value of 7/2 for the quantum number of nuclear spin V (Vanadium) in EPR? Why not other value as 5/2, 3/2, etc?
Madam may be ethyl radical shows triplet of quartet not quartet of triplet.. Please madam check it...
Thank you so much my dear jyothi mam 😍👭🙏👍
Hlo mam in CH2OH using ESR study shows how many signal?
Thank you ma'am
Parazide ke eg me nitrogen K liye b I include krke splinting lines ki value nikalenge so ans 25 lines ayega
Mam at a time 29.21 why you don't consider splitting due to nitrogen atom. Pls clear my doubt.
Ma'am for O2 spin filling order more than 14 electron not applicable here why ?(for O2 it is 16)
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 biphenyl m a and b type k jo proton h unko ek jaise nahi le skte kya
In CuSO4 . 5H2O shows how many signal if I=3/2
Well done I salute u mam
Well explained..thankyou
Thank you
Nice one
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.
Wahh wahh mam
Why is the contribution of CH2 greater than that of CH3 in ethyl radical?
Mam napthelene m to horizontal & vertical dono symmetry h so , differt h 2 honge
your organic spectroscopy playlist was removed ?
Thanku mam
Mam kewal Na ka nilkalna ho tab kaise nikalengy ,Cl-,Na+,NO2 ,ka plz mam reply
Mam your teaching style is superb. But try to provide correct data please.
At 29:30 mnt, that compound will have 25 lines, u didn't consider splitting due to nitrogen atom!
Mem aapne last me D2CH ka exampale kiya uus me 5,1 aayega ya fir 5,2 ???
mam ,last vale example me pahele doublet lekar bad me usko Quintana me split nai par sakate ? pahale kisko split karta he do kese pata chalta he ?
Mam dilute nuclie or conc. Nuclie m difference kya hota h
Mam hyperfine splitting of ammonia radical ND propyl, isopropyl radical bta do
exam h mam plz plz bta do
Mam if in H2 molecule one electrone is remove to uske pass 1 hi ele.rahega to bond kese banega ??
Kind request wonderful teaching plz videos in english
Kindly upload videos on omc for csir net exam..
The important topics that need to be covered in this topics plz..
I will :)
