Question

NMR: What can be said about proton spin decoupling?
a) It depends on the number of attached protons.
b) It slows the deshielding effects of π -electron circulation.
c) It is the same as Distortionless Enhancement with Polarization Transfer.
d) It is an instrumental technique where carbon-proton splitting patterns are eliminated.

i cant seem to understand anything about it please help! thank you!! :)

Answer 1

I believe that the answer is D. Proton-spin decoupling is used to determine," which spin-spin multipets are linked to each other and for locating absorptions that may be hidden." D seems like the best answer choice.

Answer 2

thank you!!
