31 P NMR and related questions

Discussions on Phosphorus NMR and related questions.

[@supriyabodake4366]

oh thank you so much very essential information...

[@gopalkrishnaniyogi7281]

Outstanding sir.

[@dr.sonalimahule4101]

but what makes P to show such a higher resonance frequency with a wide range than H..sorry if its a stupid query, out of books since a long time

[@saptarshiroy9568]

Is Iridium in [Ir Cl3 (PPh3)3] active in 31P NMR?

[@chemphi_AnuragM]

The add is fenominal.one of the best video in you tube

[@akankshagupta8699]

Excellent way of teaching sir

[@ritusharma9086]

Awesome :P

[@ruchishukla4521]

Sir there's a question asked in June 2016.. Duration of 90degree pulse in nmr Spectroscopy. How to calculate. Sir plz tell me

[@sapnabarad2739]

Thank you so much sir ...

[@as-bw6sr]

Ty 🤗

[@anjanavm893]

In the example of 2017 june problem, is there any coupling of nitrogen atoms, there are two types of nitrogen atoms are present, can u please share a reference for this splitting?

[@pg-trb-chemneetcsirchem5282]

Thank you sir 💐

[@mathewchristman3435]

great video btw

[@NaveenTak-ox8dc]

Dear sir, Thanks for providing such useful vedios. I request you to please make a vedio on molecular term symbols and explain how to decide gerade or ungerade. Its a request. This will be a great help for me.

[@priyaagrawal7806]

Thanks

[@sumanachowdhury473]

Thnk u sir...

[@aiimsandjipmereducation2906]

very nice vid.🙂🙂🙂

[@sautrickchowdhury89]

correct me if I am wrong but as far as I remember Pt(0) has the electronic configuation [Xe] 4f14 5d9 6s1....

[@israrul4936]

thank u sir

[@shubhamdubey7867]

thanku sir

[@shrishailshirol6131]

Sir. How many signals do PF4NMe2 give assuming that N and H donot couple( At Room Temperature and Low temperature (173K)).

[@shrishailshirol6131]

sir But how? Triplet of triplets at both the given temperatures?

[@tbhavani5349]

sir plz say how many signals in 19 F nmr of pcl2f3?

[@Learningtree1211]

Sir please make a video on Spectroscopy for JAM 2018. please.

[@akshaykulkarni3504]

In above problem each P is showing triplet then how could there be only two triplets as the structure contain four P atoms

[@ruchishukla4521]

Sir!. How N is nmr inactive.? For 14 N, I=1 and for 15N, I=1/2

[@nimeshikadiaries503]

Plz make a video on chemical kinetics for csirnet point of view

[@mathewchristman3435]

whats the difference between 31 P NMR and 31P{1H} NMR?

[@manojkumarpanigrahi8311]

Will both the triplets not couple to give 9 peaks?

[@BiswajitDas-ud6nc]

No, because the chemical shift value of the two triplets will be different enough because in one case there Cl are present and in another only N are present

[@saumyaranjanmishra7734]

can you tell when csir is going to conduct exam?

[@aseshdas3328]

hi sir.....plz make some video on structure elucidation with more example

[@vyshnavsivasankaran5886]

Thank you so much sir..u r really helpful Iam following ur videos for the last 3 mnths,its great... Sir can u plz suggest some summer internship programmes in chemistry ..

[@vyshnavsivasankaran5886]

Tnq Sir

[@jyotibhatt8117]

Sir summer internship programme keval appearing wale kr skte h ya paas out student kr skte h..

[@jyotibhatt8117]

OK and thank you sir..

[@Learningtree1211]

Sir please make a video for JAM spectroscopy please.

[@aiimsandjipmereducation2906]

sir plz solve some more questions on 31p...and 19F too...plz...

[@chetnahasija9975]

Pls explain why 3J coupling between 31P and 1H not happening in question u have discussed?I have come across a few examples where it happens,so why not here.

[@chetnahasija9975]

Gate chemistry will it be mentioned in the question

[@vasaviprasannabudumuru4876]

sir if we don't know about chemistry just we know basics then how can I prepare for csir net to crack the exam please give a guidelines to me to crack the exam

[@swativerma9238]

Sir plzz solve a ques from 31p NMR Dec 2017 for 4 marks.

[@shubhamdubey7867]

sir pls make a video spectroscopic for jam 2018

[@arunadeepthi9832]

Sir plz make a video on bio inorganic imp topics

[@monikadixit5682]

sir plz make a video on raman active molecule

[@snehlatakatheria7212]

Hello sir... Once u have said that... U have made a short notes.... Of few pages.... That can b easily read before exam....but it was lost... Please make it again....

[@chemspark9813]

pls first complete one perticular topic. I was waiting for fragmentation mode of organic comp. in mass spectrometry if possible then try

[@sakshisharma7069]

Plz solve the 31p nmr question of part c from Dec. 2017 paper

[@destinylife467]

Don't use red pen sir. Nice video sir

[@soumenpatra9301]

How many 31 P NMR signals are there when two pph3 groups in vaska's are in cis & in trans positions respectively. . .plz answer it sir

[@soumenpatra9301]

Sir iridium is active in the question

[@soumenpatra9301]

Sir the options are. . . 1) doublet, singlet ; 2) doublet of doublet, doublet ; 3) singlet, singlet ; 4) doublet of doublet; doublet of doublet

[@vishalsaini7181]

thanks sir

[@priyaarora7282]

sir P-Nmr mein Anisotropic effect pey apki koi video HAi...

[@saumyaranjanmishra7734]

I think csir is not going to conduct NET exam in december.

[@dhananjaydas5934]

Why..

[@saumyaranjanmishra7734]

you must see csir website, they have not published the selected candidate list yet, which should be published on 17 november.
