Sir i have cleared gpat with help of your videos. AIR -298 . Currently I'm doing M.pharm (Pharmacology and Toxicology ) and still I'm studying modern pharmaceutical analytical techniques subject from you !!!
Since fluorine has more chemical shift range up to 400 ppm it can be used in the study of protons which show chemical shift less than 10 ppm where fluorine is not going to interfere with study.
Two reasons we use solvent in NMR. First to prepare clear and low viscous solution. Second, to lock the magnetic field with deuterium signal. Without solvent, the magnetic field is not study and highly drifted.
hello :) Thank you so much for this great explenation. I have one question.... I know that Deuterium is NMR active, but it does not give a NMR Signal ? whats the differenz between " beeing active " and " not giving a signal ? "

Very nice explanation sir please also make video pharmaceutics
Sure I will. Keep watching.
Simply superb sir
Thank you so much
Well explained
Best described
thank you so much sir......
Well explained 👍
Thank you 🙂
Really supper sir ji
Thank you. Keep watching.
How to select chiral NMR solvent in H1 nmr. & Solvent name
Love from Pakistan ❣️
Sir please make video about glucose transporters
Definitely I will upload shortly, Thanks for watching.
@@egpat thank you for replaying sir
Sir in the last example florine also has spin 1/2 then how can it be used as solvent

Sir nmr ka pura concepts clear kardo please. Gpat ke liye bohot imp
Already uploaded few videos on NMR spectroscopy. You can find here

What is i
sir why cannot we directly place our sample in nmr?why solvent is needed?please reply

DMSO structure is wrong
