Part 1: NMR - Introduction and Basics of NMR Spectroscopy

[@pkclasses100]

At 9:30 In Alpha position, Proton will be aligned with Magnetic Field so consider North South Position of Magnet Accordingly.

[@anonymousnation5235]

I think in alpha position, north of magnet would be facing the South of applied magnetic field. Is it right sir?

[@Mr.B_2k01]

Proton follows Quantum mechanics where it would be reversed like the one you see. While the common magnet you use follows classical Mechanics where opposite pole attracts each other but quantum mechanics say same pole attracts each other. Well it is a large topic at quantum level everything changes which include the properties of the particles present.

I wish I came across ur videos during my university days, I wouldn't have failed quantum chemistry. Back then everything looked strange, see how easy you explained them. Your are indeed a great scholar.

[@syedhafeez3711]

sir you said less energy is required to flip in case of shielded proton? how is it possible? please let me know

[@pkclasses100]

If proton is shielded, then it will feel less magnetic field or less radiofrequency due to shielding and it will flip. So, ultimately we can say it less energy.

[@marvellouschemistry]

I don't understand how it is possible?

[@veenatelikicherla6782]

@@marvellouschemistry when the proton is shielded with electrons(proton is present in the nucleus and surrounded by electrons)the proton which is present inside the nucleus is not exposed to the magnetic field... Hence it does not flip to alpha position (the position where proton is in alignment with magnetic field)... Now it is easy to spin this intermediate position to beta- position because the angle here is less than 180° Where in case of Deshielded ones the nucleus is not surrounded by electrons hence it is easily exposed to magnetic field and spins to alpha position (aligned with the direction of the magnetic field).. Now the rotation angle from alpha to beta position is more than 180°..so it requires more energy.

very good lecture sir, but little confusion regarding alpha, beta positions. earlier u cald alpha position at 6:28 , but at 9:45 u cald it beta position. would be thankful if u clear this confusion.

At 6:28 representation is end to end, but at 9:45 representation of two magnets are parallel. If protons are aligned with magnetic field then it's called alpha position.
