such an easy concept to score marks...I have read this textbooks too but it had been given in complicated way..u have delivered the important concepts in very easy method which must be appreciable. sometimes listening is better than reading :) Thank U
Drago's rule was again new fr me.ur every lecture is so valuable actually.i learnt so much f esr in my pg and thought that i am good enough in it,but after watching drago's rule,i found myself wrong.thanku so much sir.
All your videos r helping me a lot .. I had almost lost my hope about clearing net exam... but all thanks to you sir... it would be really helpful and kind if you do video on quantum chemistry .
The sodium D lines are due to 2P 1/2 to 2S1/2(∆E1) and 2P1/2 to 2S1/2(∆E2) transitions.The splitting due to spin orbit coupling in 2P state of the sodium atom is........
Beautifully explained...but i have a little bit confusion ..is drago rule only applicable to coordintn compds..but if it is applicable to all..then in NH3 radical why v get 12 lines instead of 3 ....plz clear it to me if u get time ....
Sir explanation is very good. I have doubt in cu metal complex sir u said that it give 44 lines. Actually that mainly 4 signals and each signal again divided in to 11 lines. Sir please can you tell how the intensity ratio would be given to the lines.
When NH3 radical consider then H' s spin is interact with electronic spin but in case of {Cu(NH3)4}2+ H's spin can't interact with electronic spin why??
Sir u told that Pascal ∆ is valid for I=1/2 and non pascalian ∆ for I=1. What about other spins like 3/2, 5/2? Should we follow Pascal ∆ for 3/2, 5/2......??
Sir i watch ur every vedio and after that i m able to solve any question on dat topic which i find in previous papers so itz a humble request to add a vedio on daily bases.
Sir, in the last question which you have discussed , why we haven't taken G.I into picture? like the complex would form cis and trans isomers and that would lead to 1020 lines. Please try to clearify my doubt.
Good & simple explanation about ESR/EPR Basic.Great work sir! Thanks lot!

Thank U
A great content video. Drago rule explained nicely.
You try to give your 100% effort ...nice good lecture.
great sir amazing vdo & amazing explanation...thnx sir
It's very useful for me specially with more than one unpaired electron
Thank you Sir. one question here is, whether [Cu(H2O)4(NH3)2], is high spin or low spin complex? since both SF and WF ligands are present.
Thank you so much ..if possible kindly explan the concept of g perpendicular and g parallel in esr spectra which troubles a lot actually .
Thanks a lot ..
Helped me alot sir. Keep doing videos like this.
Drago's rule was again new fr me.ur every lecture is so valuable actually.i learnt so much f esr in my pg and thought that i am good enough in it,but after watching drago's rule,i found myself wrong.thanku so much sir.
Yes even for me. I never heard about Drago's rule. Thank You Sir.
Sir... you are the only ray of hope for me....in this backward area.. thanks a lot....
Very nicely explained
Sir thanks alot for uploading such a nice video.
Sir..Nice and go ahead....i have a doubt...How many peaks for O-nitrophenol?
Thanks Sir it's make easier to me ESR . I have not word for thanks you
thanku so much sir........ur lectures r really helpful...
Wow! Really a nice explanation.
You are a life saver! 💜💛💚💓
Very nice explanation of dragos rule...
sir thanku so much for the hard work u r doing God bless u sir
All your videos r helping me a lot .. I had almost lost my hope about clearing net exam... but all thanks to you sir... it would be really helpful and kind if you do video on quantum chemistry .
Sir Thank you so much, your videos are so encouraging & motivating!!!!
plz keep on posting videos
Which books should I prefer for epr spectroscopy?
Thanks it's very good explained
Sir I have 1 question... How can we know the value of I for transition elements??
Very Very helpful !!
The sodium D lines are due to 2P 1/2 to 2S1/2(∆E1) and 2P1/2 to 2S1/2(∆E2) transitions.The splitting due to spin orbit coupling in 2P state of the sodium atom is........
simply nice thank you dear
Very useful video
thank you so much sir for new information... thanks a lot
Thank you so much....take more examples of this type if possible
why is carbon not considered to calculate the splitting
Which book to follow for EPR?
UO2+ how many number of signals observed ?
Beautifully explained...but i have a little bit confusion ..is drago rule only applicable to coordintn compds..but if it is applicable to all..then in NH3 radical why v get 12 lines instead of 3 ....plz clear it to me if u get time ....
Sir, Can you please make videos on rotational and raman spectroscopy.
For CD3 its 1:3:6:7:6:3:1
Yes absolutely,I was just about to confuse ...but finally I got it.
i have doubt in molecular spectroscopy... Please suggest about it.
i have confidence about EPR thanks u sir ...
In case of non pascal triangle it should be 7 not 9 in case of n=3
Thank You so much sir for your wonderful explaination...But I had a doubt that ammonia is a diamagnetic, right? So will it show any signal?
video time 11:30
Sir please make a video on Raman spectroscopy as well
Can you plz make a video on mossbauer spectroscopy
its really helpful 4 us.
thanks a lot sir
For ethyl radical ..is it 12 lines....??
Very nice sir.. Please update the video of mosbaur spectra.. And recomend the book of esr and mossbour spectra
Sir please say where I found the problem solved on esr. Nqr. And mossbour spectra
Thankyou so much sir ....great job..
Thanku soo much.. Plz explain mossbauer too
Sir explanation is very good. I have doubt in cu metal complex sir u said that it give 44 lines. Actually that mainly 4 signals and each signal again divided in to 11 lines. Sir please can you tell how the intensity ratio would be given to the lines.
Which Books for esr and mossbaeur for inorganic spectroscopy can u plz suggest
Sir everything i can understand
But how can i got the I value for different elements
It is given in exams
thanks a lot sir to make this topic easy
How many epr line shows phenyl radical..
sir if you find some time
also cover mossbauer and thamks alot
Its too helpful. Thanks bro
Sir, please explain Kramer's degeneracy related with ESR
in NH3 radical why Hydrogen take part in the spilliting? N is magnetically active
Sir iz Drago's Rule iz applicable for only Coordination compounds...In NH3 redical molecule H3 participates...
super sr.....
When NH3 radical consider then H' s spin is interact with electronic spin but in case of {Cu(NH3)4}2+ H's spin can't interact with electronic spin why??
In 2013 june Q.) The no. of EPR signals observed for Ni(II) complex is
The answer should 2 . Am I right?? but the correct answer as given is 1
Please give me response sir
Why we count equatorial axial in case of [Cu(H2O) 6]2+ complex but not count in case of [Ti(H2O) 6]3+ complex?
awesome sir Ji numerical ab ban raha Hi. thanks
Sir could you please explain the ESR spectrum of NO radical?
if in [Cu(NH3)4] ..H is not participating in splitting ,then why in NH3 it is participating and showing 12lines
preeti awasthi same question here
Bcoz H in NH3 is alpha and in complex it is beta. N beta H doesn't show lines
According to dragos expt
How do you calculate I value.... For an element
You said directly for h half
D 1
N 1
Cu 3/2
You can't. They're experimentally determined.
Sir u told that Pascal ∆ is valid for I=1/2
and non pascalian ∆ for I=1. What about other spins like 3/2, 5/2? Should we follow Pascal ∆ for 3/2, 5/2......??
No you can't follow PASCAL triangle for other than half
For 3/2, 5/2 nd other more, use only non pascal. Pascal is for only 1/2
sir when you will uplode next vedio for group theory
sir.... it is greatly helpful... but ur videos are not clearly shown.... u have to use high resolution power camera..... this is an suggestion
is this part imp for jam too?
Sir hyperfine splitting of n-isopropyl radical ki bta do
Plz Sir exam h
Thank you so much for the video really appreciate it
ESR spectrum of a solution of [Cu(acac)2] CONTAIN HOW MANY SIGNALS??
Could you please provide the next video link of EPR where you talked about parallel and perpendicular
Sir in ammonia we don't have unpaired electrons but we get splitting pattern... How ?
Sir can pls make a video on rot.,vib., n raman spectroscpy
Sir i watch ur every vedio and after that i m able to solve any question on dat topic which i find in previous papers so itz a humble request to add a vedio on daily bases.
The number of EPR singnal observed in octahedral Ni (II) complex is........
Plz explain this question sir
Good class
1.∆E2+∆E1
2.∆E2-∆E1
3.∆E2+∆E1/2
4.∆E2-∆E1/2.
Sir,last two options are whole divided by 2
Sir if you don't mind could you please provide us some classes on NMR
IR spectroscopy
Which are esr active?
B2,O2,Ñ2,F2,C2
can u plz upload a lecture on asymmetric catalysis viz cbs catalyst,proline etc.
In last example sir H atoms of NH3 do not participate in splitting ?? ??
Why sir ???
Sir, in the last question which you have discussed , why we haven't taken G.I into picture? like the complex would form cis and trans isomers and that would lead to 1020 lines.
Please try to clearify my doubt.
sir pls make a video on inverse spinal and normal spinal compounds....
sir make a video on nanoparticles and instruments to determine the nanoparticles
Sir plz make video on quest of Fisher and schrock carbene
In organic molecule hydrogen is attached to carbon wh8ch is inactive so Dragos rule ?
sir if spin is other than 1 then we use pascal traingle or non pascal ????
thankeww sir
Sir this should be done for jam ?
sir firstly thank u soo much...and if possible plz explain how to find spin of atom..
sir in Dec -14 , question no. 55 why cl is not participating in finding signals ...plz explain..
sir how can u determine the spin of Cu and Ti as 3/2, plz explain....
same question sir
ok... thanks sir..
Yes sir please make video on calculation of spin.
sir,napthalene radical shows 2^7 lines in esr spectra and napthalene anion shows 25 lines..
What if more than one unpaired electrons are present? EPR inactive?
Yeah got the answer at the end! Love you and respect you as a personality!
Thank uuu Sir thanku so much for this
Sir plz explain one ques it is from June 2013... The no. Of EPR signal observed in octahedral Ni (II) complex is :
Sir please explain physical chemistry topics too
Sir what is the Kramer's doublets in cr(3) ion ... Plzzz explain
I would like to practise more problems of esr spectrum of molecules...which are the best reference books for esr spectroscopy..what about pyrazine?
Thank you sir..do you have e book of Drago..in lib gen it is not available..
Hi sir , hpy evng for you. ..
I have small doubt. . how to you told Cr I = 5/2, Ti & Cu = 3/2. . please explaine for me. .
