Ok, so if I've got this right, "relaxation time" referrs to the time taken for an excited nuclear particle to return to it's normal spin. And charged nuclear (like hydrogen) can change the time for a spin to return to normal, generally speaking this change is an decrease of time taken to return...
I am trying to figure out why unlike H-1, NMR output on C-13 is not proportional to types of carbons. Which is to say in a molecule with two CH3 and two CH2 The peaks for the related hydrogens would be one unit tall and 2/3 unit tall. Meanwhile the mentioned carbons would not by nessity have the...
