Anisotropic effect in 1H NMR
HTML-код
- Опубликовано: 9 сен 2024
- Magnetic anisotropy means a "non-uniform magnetic field". Electrons in π-systems (aromatics, alkenes, alkynes, carbonyls etc.) under the influence of external magnetic field induce a magnetic field which is anisotropic in nature ie at some places it is parallel to the external magnetic field and at other places it is opposite to the external magnetic field. As a result, the nearby protons will experience 3 fields: the applied field, the shielding field of the valence electrons and the field due to the π-system. Depending on the position of the proton in this third field, it can be either shielded or deshielded.
Best lecture
Thanks for watching
Sir , today for the first time I watch Ur channel & this video ...Ur really explained in soo simple version ... thanks
Thanks and welcome
Thank you sir for the crystal clear explanation 🙏 .
Why ring current moving anti clockwise they also can clockwise so all shielded change into deshielded???
I think that is because, by Lenz's Law, induced magnetic field opposes the change in the external magnetic field. So in the loop, as external B increases, the induced current will be anticlockwise.
omg found it so useful , thank u sir for such a nice explanation.
Very nice explanation sir
Thanks and welcome
Very good explanation
Tq fr ur valuable video and nice explanation sir ...
Keep watching
Thank you very much , this is very kind of you !
You are welcome!
Good
Very helpful sir...Thank you sir
Thank you very much sir.it is very useful to me
Welcome!
easy to understand 👍
Helpful !!!
😀 nice sir
Thanks and welcome
So helpful👍👍👍
Glad it was helpful!
Thank you sir
Sir, How do get negative value in 1HNMR? The range in 0-12ppm
Much helpful
Thank you!
Pls do more sir
❤
Tq sir could u pls explain abt chemically and magnitically equivalent and non equivalent and naming of it
Sure
Hello Raja,
I have uploaded video on chemically equivalent and magnetically equivalent nuclei in NMR. Below is the link for the same:
