[@shabnamdan7898]

Thank you for this. You explained this really well. Must admit that you're a great teacher :).

[@animeshmukherhee7036]

Nice explanation sir.. It cleared me all the doubt about the g value.. My humble request is please upload all the videos of epr and mossbour spectra before the December 2017 csir Xm.. Thank u

[@krishnenduchandra2093]

It 's really awesome...i understand this topic very well....will u upload some physical chemistry topic like quantum chemistry

[@neelammarwaha3552]

Please answer this question In the epr spectrum of tetragonal Cu(ll) complex,when gll>g_l_>ge the unpaired electron resides in the orbital ?

[@paritadetroja2615]

Thank you sir... For very precise n useful lectures..... Ur explain things from the point of view of application that's very useful n time saving also.... Thank you sir....

[@chemistrypoint138]

Sir the formula for a=ro *R is wrong it is ro = a/R

[@aishakhan9976]

Sir calculation galt aa rhe h. 05/.0023 aapk kaise. 046 aa rhe 2.173 aa rhe h

[@nabaankurhazra953]

Sir awesome... U r one of the best teacher in my life. Probably the best...

[@chemshort5225]

As it is trigonal bipyramidal,dzx,dyz will be of lower energy.so electron enters into either f them but not dxy.so as electron density defines g,and gxy is g perpendicular,I can predict g parallel to be greater than g perpendicular in other way.i hope u understood sir

[@kamalpreet5695]

Sir u explained so well....thnk u so much ....u r really a great teacher

[@abhishekraj2194]

sir strategy that u have told which chapters1to be completed will help to get good rank in csir net exm

[@principleinstitutetelugu8274]

Sir plz organise all videos its confusing to follow one after another where is part 3 sir

[@pgboy5149]

sir what if they ask about d7 complex..so what will be gll , g perpendicular and g ? as in d7 no electron in either dz2 or in dx2- y2. plz ans

[@arvindjain1317]

Co3(CO)9Se...how many esr spectral lines are there sir??K3Mo(CN)8...esr spectral lines?in these complexes how can we find value of I sir?pls help me sir..

[@kanikalalit1153]

u have explained it so well.my all concept are crystal clear.tysm

[@supriyabodake4366]

very nice lecture sir ,today i got very imp information thank you very much.

[@reetikachauhan9810]

Nicely explained..waiting for next part

[@neshthadev8881]

I have one doubt suppose if we have complex [Co(CN)5(NO2)]3- So major product will be dat in which CN is attached with NO2 not CN attached to ONO becoz of symbiosis as CN is soft prefers to bind with soft so my doubt is how many esr lines would be there in dis major product. In (CN) 5 N is attached to inactive C so we will consider 5N then what about N of NO2?????

[@abhishekraj2194]

sir can you plz tell from where and what we can practise to attempt aptitude questions in csir net exam

[@ruchishukla4521]

Sir.... Zero field splitting and Kramers degeneracy... These topics r imp or not?

[@ashwinigaikwad2819]

Sir in above video according to the formula a=£ *R it should be R/a to calculate electron density

[@pratibhamourya7839]

Thanks sir...Very helpful.... Requested to do video on NQR spectroscopy.....Or if u had any notes on NQR spectroscopy kindly share.

[@abhishekraj2194]

sir Shriver and Atkins is good for preparing inorganic all topics

[@ruchishukla4521]

Sir... Will you upload a video on zero field splitting and Kramers degeneracy

[@Chem_tons]

sir where is the 3rd part .....which u talk about in the above vedio

[@abhishekraj2194]

it will be very costly to buy it from market can we download it online

[@animeshmukherhee7036]

Wish u happy durga puja. Enjoy with ur family sir...

[@abdevilliers7112]

Small mistake happened,but it's not a problem.this epr topic what ever you teached excellent than our proffeser .thank you.

[@pratibhamourya7839]

It's really awesome and very helpful ☺️☺️

[@abhishekraj2194]

sir huheey will be sufficient for studying inorganic

[@ashwinipande102]

SIR CAN YOU MAKE VEDIO ON GROUP THEORY AND CHARACTER TABLE RELATED PROBLEMS.....

[@abhisekbanerjee7057]

Thanks a lot for keeping my request .now the g concept is very much clear to me . Frnkly speaking i have become your fan .:)

[@abhisekbanerjee7057]

Ok definately i will start to solve questions on this concept .but can i get your email id atleast ?? so that if i face any problem i can share that with you .

[@abhisekbanerjee7057]

Thank you so much ..

[@shyamsharantripathi4187]

Sir, in NMR, esr and other....what the mean of resonance?

[@rashmirawat9041]

Thnku sir for ur support nd hardwork for us...sir plz solve the question no. 89 from 16 dec set b(part c)..I m solving this problem bt not reaching the correct ans

[@AjaySingh-sm8hb]

thanks sir . your videos are very helpful. i m very grateful to you sir.

[@Libinthomas92]

Sir, is d9 Cu octahedral system dynamic ?

[@chanchalsolanki2791]

this is awesome and sir plz make a video on massbour spectro. part 2nd

[@aasthaaggarwal348]

Sir, time 13:23,here the coupling constant value (a) is given for hydrogen, not for carbon?

[@aasthaaggarwal348]

Gate chemistry OK thankyou sir

[@harshitajain2486]

Thank u sir, for d explaination ..but i need to know abou the reference book in which i found Mcconell relationship....pls tell

[@deepu8365]

McConnell equation is a=Q* row.. Where a= hyper fine splitting constant.. Row= spin density.. Q= an empirical constant. The value of Q in between 2.0 to 2.5 mT.... Sir Little confusion between this equation and the equation u said..

[@deepu8365]

I think sir made a mistake in calculation. Pls clarify the calculation of the 2 problems..

[@abhishekraj2194]

sir plz make video on transitions in homonuclear diatomic molecule

[@dixjain9635]

what is relation between A parellel and A perpendicular wrt to g parellel and g perpendicular.....in case when solution of cu+2 in water frozen????? and what is epr line of hypothetically NH● redical????

[@dixjain9635]

i have one more doubt in net examination. asking about cu+2 and cr+2 tetrahedral compound not octahedral compound then why u explaining the jhan teller distortation in octahedral compound ....???

[@mannusawal7944]

Thank You so much sir for clearing all the doubts

[@animeshmukherhee7036]

Sir when u upload mosbaur spectra part 2

[@abhishekraj2194]

sir ap tanabe sugano diagram kb karwayenge

[@sapnabarad2739]

Hello sir ...hyperfine line for [Cu+4(en2] ?? sir ethylene diamine so we should consider 4 N na ? .. sir i got 36 line is it correct ?

[@sapnabarad2739]

3 unpaired e yes sir ..I forgot to multiply with 3 unpaired e... Thank you so much sir for this correction ..

[@pgboy5149]

Sapna Barad ...why multiply by 3 electron? Cu is 1 electron system na? Plz reply

[@BioML]

sir how there is 3 unpaired electrons are there

[@chemistry-basicstoadvanced714]

Angel D Shmuel Take it as tetrahedral complex... It gives...e(4) t2 (3 unpaired)

[@minakshiverma9978]

U are awsme sir . Nice explantion .. it cleared my all dought fr g value... plzz upload the video for mass spectra its a rqst sir....

[@minakshiverma9978]

I am wi8ing sir

[@sapnabarad2739]

very helpful lecture thank you so much sir ...

[@Himanshugautam525]

Please sir provide us lecture on physical chemistry

[@abhishekraj2194]

sir have u made epr part3

[@MS-bg5nk]

Sir can you make a video on organometallic chemistry, like important topics in there?

[@MS-bg5nk]

Gate chemistry ok. thank you sir

[@sobiakhan709]

When u r going to upload the 3rd part..

[@abhishekraj2194]

or any other book we should go through

[@abhishekraj2194]

aur sir when u will explain orgel diagram

sir nice explation but what written in black board not clear

[@bhawanasaklani4802]

take the video offline...u will get better result...

[@sukhchandraadey6454]

sir ji a=rho into R then formula should be =a/R

[@nabaankurhazra953]

Sir I can't find ur 3rd lecture on ESR... help me

[@nabaankurhazra953]

Thanks sir

[@sooryas9301]

Sir, could you please help to solve this. In the EPR spectrum of tetragonal Cu(II) complex. When gII >g⊥> ge the unpaired electron resides in the orbital 1. dxy 2. dx2-y2 3. dz2 4. dxz (CSIR June 2011) Thank you..

[@sooryas9301]

As I understood, I got the answer dz2. Is it correct?

[@zpluschemistry9380]

options 2 is correct answer

[@sooryas9301]

Thank you..

[@mohdsufiyanchauhan6068]

2. dx2-y2

[@sudheer2643]

Thanks for the great video sir

[@Supdada]

Row = 0.05÷.0023=21.37 i m getting... But u gave like .4. and i m confusing... Clear me in possible way sir.

[@Supdada]

Tk. Sir

brother would u upload video on mass soectro ?

[@chemysteryassets]

ok ok :)

[@swagatikadash6836]

Please upload more videos on esr

Sir apne row= R/a likha hai Please row= a/R hoga

[@rahulaochar]

thanks Ek number Sir

[@deepu8365]

Sir pls make esr 3rd part.

[@ruchishukla4521]

Sir... In dynamic JT distortion electrons are delocalised.. But you said.. That they are localised...

[@deekshasaini9607]

thnk u soo much sir......
