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.

Sir. How many signals do PF4NMe2 give assuming that N and H donot couple( At Room Temperature and Low temperature (173K)).
@shrishailshirol6131
@shrishailshirol6131 6 лет назад

@manojkumarpanigrahi8311
@manojkumarpanigrahi8311 6 лет назад
Will both the triplets not couple to give 9 peaks?
@BiswajitDas-ud6nc
@BiswajitDas-ud6nc 5 лет назад
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
