Good explanation, really highlights the key points and how to view the effect. Do you by any chance have videoes on the other effects present in Dynamic Nuclear Polarization, such as the sloid effect, cross effect or Thermal mixing? Would love to see an explanation for those

Dear Sir, Thank you very much for such a nice explanation. I do not understand why small molecules render double quantum transition and proteins do zero quantum transition. I am using NMR for protein. I will be highly obliged, if you will make me understand why small molecules show double and big molecules show zero quantum NOE. Thanking You Sincerely Bikash

I just finished watching your videos on COSY, TOCSY, NOESY and this and they are absolutely brilliant. One question on this video: you said that W2 (double quantum transition) is disallowed by quantum mechanics - I thought if something is disallowed by a fundamental law of physics then it's pretty watertight! What do you mean when you say it's disallowed?
@nichelleuhura60408 жыл бұрын
+gammaray0wn Disallowed (usually called forbidden) usually means the probability of it happening is very long, but not entirely impossible.

@MadhuryaKakati6 жыл бұрын
Does this mean that when relaxation of the interesting nuclei happens after saturation, it will happen to the new and different configuration instead of the thermal configuration? As far as I understand only this can change the intensity

@allthingsafrika7 жыл бұрын
I am still confused by something. When people mention population difference, they talk about many spins of the source going to the up state and then going back to the down state. I thought that a proton only has one nuclei and therefore one spin so how can there be a population of spin?
@juanfelipeavellanedatamayo62296 жыл бұрын
Remember that you are influencing your nuclei under a magnetic field, what polarizes his magnetic momenta at two posible values, +1/2 and -1/2, each one with different energy. Then, you have a portion of that nuclei in each state of energy, and that population have to favor the transitions, allowing the magnetic resonance when you apply the radiofrequency... sorry for my bad english :/

You're right, I just went to the molecule, and even to a portion of sample, directly.
