Hello.... I am not from the physics background so was struggling to understand this; you explained it so well that all my basics about NMR is now clear.... Thankyou so much!!!
Your way of explanation is too good. Truly this video is helpful for easy to understand about NMR spectroscopy . I 💜 it. Thank you so much for valuable information.
Hello Sir... superb explanation...😊 u really made NMR so easy.... please do more videos on COSY, NOESY, FT NMR, 13C, SPIN Relaxation Phenomenona and Other concepts that are present in NMR spectroscopy
Hi, Nice explanation.. It would be better to describe why Resonance term is used in the technique.. and please check once regarding "No spin " in "No external magnetic field". The concept is, in no external magnetic field nuclei with 1/2 spin will be arranged in random, when an external magnetic field is applied, the nuclei with 1/2 spin will allign to the field. And further is as described. Ignore it, if it is irrelevant.
Ya, that's a good point. You are correct, as you said, in absence of magnetic field nuclei will have random spin and they produce a small magnetic filed. These nuclei will have intrinsic angular moment but the net spin of all nuclei is very nearer to zero due to random orientation of individual spins. So practically it can be considered as net zero spin compared with nuclei with spin oriented with or opposite to external magnetic filed when it is applied. Thanks a lot for your interest and suggestion.
Thank you for this helpful video! I really appreciate it :) On a side note - I noticed that at 11:09, the m value for I = 0 should be 1, not 0 (as presented).
When I value is 1 or greater it results in non-spherical charge distribution resulting in signals with variable line width which are not easy to study. But when I=1/2 it leads to spherical charge distribution which is easy to study. That's why nuclei with I =1/2 are selected for NMR spectroscopy.
That's great. You are right. So these are the quadrupolar nuclei. But here in this video we are discussing NMR spectroscopy for pharmaceutical analysis where we study nuclei mainly like proton, and carbon in organic compounds which have I value as 1/2. As you said, quadrupolar nuclei are useful to study inorganic nuclei like Cl and B. Thanks for your interest and watching the video.
Nearly all of the information presented in this video is wrong. The claim that you can only observe NMR signals from spin-1/2 nuclei is especially agregious.
