NMR IV
To make effective use of NMR we must use superconducting magnets. At a given Bo nuclei can
be excited from one spin state to another
by absorption of radiation of
radio frequency (MHz):
DE
Bo
E
1. DE =
hn
From the
figure:
2. DE = const. x Bo
2. DE = const. x Bo
Combining 1. & 2.
n = const.’ x Bo
