Calculate the frequency separation of the nuclear spin levels of
a 13C nucleus in a magnetic field of 15.9 T given that
the magnetogyric ratio is 6.73 × 107 T-1
s-1.
Ans=______ MHz. (Note: because the magnetogyric ratio of
13C nucleus is only about 1/4th of that of a proton, the
frequency of resonance is also only about 1/4th of the proton
resonance frequency in the same instrument.)
