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........
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??
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.
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.
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 june 2017 question regarding ESR, (R3 Ge)2 on photolysis gives a radical which shows ESR spectrum . The ESR signals carrying the signature of 73 Ge (I=9/2) are in terms of a)nine lines b)ten lines c)two lines d)one line .But im getting it as 19 lines sir what's my mistake Im not getting
Jahn teller distortion is not considered in [Cu(NH3)4]2+ but in [Cu(H2O)]2+ it is considered, so taken two environments for Cu in the later one. why? Can u please tell me
Sir CH2 free radical and D both of give 3 ESR line in cpds but why CH2 free radical intensity ratio is 1:2:1 and D intensity ratio is 1:1:1 I am little confused sir
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
Good & simple explanation about ESR/EPR Basic.Great work sir! Thanks lot!
You try to give your 100% effort ...nice good lecture.
A great content video. Drago rule explained nicely.
Helped me alot sir. Keep doing videos like this.
It's very useful for me specially with more than one unpaired electron
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.
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.
great sir amazing vdo & amazing explanation...thnx sir
Thanks Sir it's make easier to me ESR . I have not word for thanks you
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 thanks alot for uploading such a nice video.
Which book to follow for EPR?
Sir I have 1 question... How can we know the value of I for transition elements??

plz keep on posting videos
sir thanku so much for the hard work u r doing God bless u sir
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 ..
Thanks it's very good explained
why is carbon not considered to calculate the splitting
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........
thanku so much sir........ur lectures r really helpful...

Sir everything i can understand
But how can i got the I value for different elements
It is given in exams
Its too helpful. Thanks bro
sir,napthalene radical shows 2^7 lines in esr spectra and napthalene anion shows 25 lines..
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 ....
ESR spectrum of a solution of [Cu(acac)2] CONTAIN HOW MANY SIGNALS??
Thank you so much....take more examples of this type if possible
in NH3 radical why Hydrogen take part in the spilliting? N is magnetically active
How many epr line shows phenyl radical..
Sir, Can you please make videos on rotational and raman spectroscopy.
Which Books for esr and mossbaeur for inorganic spectroscopy can u plz suggest
simply nice thank you dear
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
Sir could you please explain the ESR spectrum of NO radical?
Sir in ammonia we don't have unpaired electrons but we get splitting pattern... How ?
Sir please make a video on Raman spectroscopy as well
Sir iz Drago's Rule iz applicable for only Coordination compounds...In NH3 redical molecule H3 participates...
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.
Very Very helpful !!
its really helpful 4 us.
thanks a lot sir
Thanku soo much.. Plz explain mossbauer too
Sir, please explain Kramer's degeneracy related with ESR
Please give me response sir

i have doubt in molecular spectroscopy... Please suggest about it.
i have confidence about EPR thanks u sir ...
Very useful video
Ti(3) will also under go JT(Zin) .. as the effect is not so pronounced therefore not taking this under consdrsn?
Can you plz make a video on mossbauer spectroscopy
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
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
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.
thanks a lot sir to make this topic easy
is this part imp for jam too?
For CD3 its 1:3:6:7:6:3:1
Yes absolutely,I was just about to confuse ...but finally I got it.
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.
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 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.
Which are esr active?
B2,O2,Ñ2,F2,C2
Sir what is the Kramer's doublets in cr(3) ion ... Plzzz explain
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
Why Drago's rule not applied in NH3 radical?
Reetika Chauhan did u find the answer??
Gate chemistry sir could you please explain the reason for this?
why dont we consider Jahn teller distortion in Ti(H2O)6 complex
Sir hyperfine splitting of n-isopropyl radical ki bta do
Plz Sir exam h
Sir this should be done for jam ?
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!
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..
Sir chromiun di spin 3/2 ni hoti??
Why the spin of cu is take as 3/2 for evry oxidation state
Sir Please tell me I values for Co, Mn and cr ?
how many esr lines are there in the compound[ Cr(H2O)6]3+?
Thank you Sir!
sir if you find some time
also cover mossbauer and thamks alot
sir if spin is other than 1 then we use pascal traingle or non pascal ????
thankeww sir
sir how the spin of cu is 3/2 ? pls explain ..
In organic molecule hydrogen is attached to carbon wh8ch is inactive so Dragos rule ?
Sir in which book i can come across this drago's rule...
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..
Lines for (CF3)2N radical?
Sir, how many signals will be there in the EPR of DPPH and TEMPO?
thank you sir.. and will you give some last minute tips for the GATE 2018 aspirants also?
in the anthracene molecule ,how Ha and Ha are different??because they are belonging to the same environment..so how?
sir june 2017 question regarding ESR, (R3 Ge)2 on photolysis gives a radical which shows ESR spectrum . The ESR signals carrying the signature of 73 Ge (I=9/2) are in terms of a)nine lines b)ten lines c)two lines d)one line .But im getting it as 19 lines sir what's my mistake Im not getting
but but two germanium atoms are their no sir
oh ok thank you sir
Sir if you don't mind could you please provide us some classes on NMR
IR spectroscopy
Sir can pls make a video on rot.,vib., n raman spectroscpy
sir plz tell me ,how many esr lines are possible for [Cu(NH3)6]2+ complexes ,here also the effect of john teller distortion will happen?
Jahn teller distortion is not considered in [Cu(NH3)4]2+ but in [Cu(H2O)]2+ it is considered, so taken two environments for Cu in the later one. why?
Can u please tell me
Sir CH2 free radical and D both of give 3 ESR line in cpds but why CH2 free radical intensity ratio is 1:2:1 and D intensity ratio is 1:1:1
I am little confused sir
different intensities due to pascaline and non pascaline trangle madam
In the last question, why don't we consider JT distortion
