NMR is a widely used spectroscopic method to deduce chemical structure. It has become a central tool for chemistry, medicine, materials science, and engineering. This animated video shows the behavior of nuclei in a magnetic field, magnetic resonance, and explains how the NMR spectrum is used to understand chemical structure. Rather than go into the quantum theory and mathemantics of NMR, the goal of the video is to provide a visual model to help students and life-long learners gain a deeper understanding of NMR. It should be noted that the animation of the continuous spin state transitions is not representative of the actual quantized behavior of the spin states. For viewers interested in further exploration of NMR theory, please refer to textbooks or on-line sources such as:
en.wikipedia.o...)

Hopefully, there will be more visual teaching materials like this one in this channel and more professors and students can find these clips here. Thanks for making this video!

Worth pointing out: The pulse is not directed along right angles, it is in fact directed axially along B0, but the radio waves are circularily polarized, so the B1 field in the radio wave is actually spinning in the xy plane. It's the B1 field that is at right angles, but constantly spinning at the Larmor frequency (omega0) of the protons. This B1 spinning field forces the nuclei to gain an additional preccesion motion around itself, at a rate of omega1 (omega1 = gamma * B1) and the overall magnetization is then manipulated as we please.

I'm not sure individual spins actually behave like shown at 2:01, they can only precess along the Z azis, the incoming radiation simply flips them from +1/2 to -1/2 and induces some coherence between their precessions, the following decays of the precessional coherence (T2) and the decay of the non-equillibrium population of -1/2 oriented spins (T1) together give rise to the collective FID behaviour of the global magnetization vector. As i understood it, it's only the global M vector that has this "classical" decay evolution that we detect as a FID signal, the vertical component of the magnetization being purely a result of the populations of +1/2 and -1/2 orientations, and the x-y component evolution of the M vector being the desyncronization of precession of the entire population of spins.

@adriaanberger1930

This is also how I understand it. It would be responsible if the creator made a note in the description that the animation of the spin state transitions as continuous is not representative of the salient quantum-mechanical model required to predict MRI phenomena.
@ScienceSketch
@ScienceSketch 3 года назад
Hi Adriaan, thanks for your input and absolutely correct. My intention with the video was to create a visualization of the decay of -1/2 spins in T1 to give the observed FID behavior. I urge the viewers to delve more deeply into the mathematics and quantum theory behind NMR. I will take your advice and add a comments to the description. Thanks for subscribing!

@ScienceSketch
@ScienceSketch 3 года назад
Thanks very much, Hedgehog. The relationship between shielding and frequency depends on the Larmor equation. The higher the magnetic field around the nucleus (less shielding), the higher the frequency. More shielded nuclei will experience a lower magnetic field and will have lower frequency. Stay tuned for NMR II coming out soon.

1:54 - does this pulse have to be mached exactly to rotate the nuclei? Is it possible that in a given molecule some atoms that are strongly shielded / deshielded would be too far of the tune to be rotated by that RF pulse? Or simply the pulse contains a spectrum of frequencies and all nuclei will find matching tune to rotate?
@ScienceSketch
@ScienceSketch 9 месяцев назад
Thanks for your question. You answered it in the last sentence. The short Rf pulse has a spectrum of frequencies and will excite all the nuclei.
