Category: CSIR June 2012 plz answer this The carbonyl resonance in ¹³C NMR spectrum of [(η⁵ - C₅H₅)Rh(CO)]₃ (¹⁰³Rh, nuclear spin I = ½, 100 %) shows a triple at -65° owing to the presence of 1. Terminal Co 2. μ2 - Co 3. μ3 - Co 4. η⁵ - C₅H₅
This question has created new doubt.sir plz also explain y in eta4-C8H8Ru(CO)3 carbonyl signals r not observed,we get only 4 bcoz f ring carbons, and in this case it is seen?
Can u please help me with the question? Complex [Cr(bipyridyl)3]3+ shows red phospherscence due to transition??? It was asked in june-16 csir net que no 71 in booklet A
Cr d3 =4F(Groundstate term).As per phosphorescence is spin forbidden transition and also occurs when electrons comes from excited state to ground state .Hence,transition 4A2g_2Eg is responsible for the phosphorescence.
@sapna Barad Sir, already told that orgel diagrams only for high spin complexes. But ur question is not wrong. As it hasn't unpaired electron. So it gives symmetric term symbol
As u knw for d3 the term is F and P.. The transitions are as such as explained in above video.. From A2g-> T2g, A2g->T1g, A2g->T1g(P).. But the question says that red phosphorense so phosphorescence is the emission from triplet state to ground state and the options are from ground state except Eg->T1g.. So this is the correct answer.

Very much explanation....plz make a video on ..... correlation diagram for d2 in octahedral complex
Fully enjoyed learning chemistry for the first time
I think at 18:40 the direction of arrows for absorption & emission are wrong.plz check.
sorry my mistake.it is correct.
Sir please make video on tanabe sungano diagram..
When you are free time please provide us one class on
Sterio chemistry plz sir
Tq very much sir.....this video z really very useful........ And cleared all my doubts....Once again tq...
awesome explanation...plz make video on tanabe sugano too.
Did u make the video on Tanabe Sugano diagram?
I couldn't find.
Have u upload the video on T-S diagram and Racah parameter already?!
Kindly make video on correlation diagram.Yours videos truly play pivotal role in one's(student pursuing chemistry)life;Thanks so much!
In H....T1g comes for two time ...why...& Is it possible?
superb explantion sir
Sir, to get the p term for d2 we need to violate the hunds rule. Is that ok?
sir, can u make a video describing the method to make this kind of educational videos
sir 2017 gate log beta wala question discuss kr diye plss metal konsa hoga
Very nice concept
very helpful video....thank you so much sir.
sir in complex cr(nh3)63+ transtion from 4a2g- to 2eg how is it
Sir. which book will be best for practice problems on inorganic spectroscopy ??
Sir for d2 and d7 Oct the second transition is from T1g to T1g(P) or T1g to A2g plz reply sir it's confusing
plz explain Tanabe-sugno diagrame and racah parameter
Sir i really like your videos....please try to explain tanabe Sugano diagram and Racah parameter
Sir plz also explain electric dipole allowed transition
Hi sir ...plz make video in homogenous and heterogenous catalysis
Sir.... it seems good to c u at front of board instead to it
Pls give a video of tanabe sugane diagram
Easy to understand ..nice ...👍
Sir please make a video on tanabe sugano diagrams... It will be very helpful sir... Please 😊

Triplet of carbonyl carbon indicates the each CO is attached with chemically equivalent two Rh atoms that means μ2 - CO Complex .Answer is 2
Its fantastic......
Sir, what is the order of the energy in Mulliken symbols for the spectroscopic terms.???
very nice, sir please send more videos
sir,what about strong field(low spin) octahedral complex ?
Is orgel diagram is in syllabus of iit jam
Please make a video on tanabe sugano...and corelation diagram
suprb video plss sir upload video in which solve some last years net exam ques related to orgel diagram topic
you explained it in very easy method thankyou sir
Sir what will the ground state term for Cr ion in [Cr(CN)6]-4 . I m getting a wrong ans for it asked in gate 2017
Is it 5D
Sir orbital angular momentum 5..how?
I am also not getting it sir
Complex (cr(bipyrid))3 3+ shows red phosphorescence due to transition? ans is 4a2g- 4t2g
Am I right
But ans is 2eg -4ag
How?
Ok. Thanx sir
U r doing a gr8 kob sir👍
Excellent
Please use board sir... That is very comfortable for us to understand... Ur other board lecturers are very use full...
Sir, give me a suggestion on a good asymmetric synthesis book
Thank you, sir. And i have special interest in coordination & organometallics, any specific book for that sir?
very well explaining sir....thnku
Can u please help me with the question?

I got my ans....thanq sir
Very good Sir.
Pls introdune tenabe sugano diagram
Your Vedios are really helpful🙂 can yu please share how to calculate conversations of transition corresponds to ground state term..
sir plz upload video on quantum chemistry.
Thank u very much for such a good n quick response
Naku ardham kavatam leydhu d1tod10 one by one explain cheyyu raa
Sir plz upload lecture on optical isomerism.I face lot of problems in it.Only u can guide me on that.Accept my love ,care and respect sir.
Thank you very much sir
Now my doubt is over regarding the topic thanks a lot sir
And sir wish you a happy dussera sir
Hi Sir, could u explain WHY the Orgel diagram looks like that? Why does it curve up for T1(P) and curve down for T1(F)
Due to repulsion of same levels think so
No dear..it's for symmetry interaction involved between the same energy levels
nice
good
Sir plx upload a video on tanabe sugano diagram ......
sir ground state term symbol for [Mn(Cn)4]-1 sir i got 4 T1(F) sir is it right ?
yes sir got it ..CN is low spin ...sir then how can we solve this question ? grond state term symbol for [Mn(CN)4]-1 ...is this question wrong ?
@sapna Barad Sir, already told that orgel diagrams only for high spin complexes. But ur question is not wrong. As it hasn't unpaired electron. So it gives symmetric term symbol
Sir, can u pls help us with quantum chemistry.....pls cover syllabus for gate & net......pls
Thank u sir
Clarity ga explain cheyyandi d1 to d10
Thanks sir for considering my request
Sir pls can u give ans for Q no.75 related to transition asked in csir net june 2016 set c
