What wavelength of radiation would you use to observe the
following processes
a. Reorientation of the spin of an unpaired electron of its heme
group in a
strong magnetic field (say, 10^4 gauss)
b. Reorientation of one of its proton spins in a strong magnetic
field (say, 10^4
gauss)
c. Reorientation of the dipolar protein (u ~ 10^2 D) in an
alternating electric
field of 30 volt c m-
d. Excitation of the vibration of one of its C=O groups
e. Excitation of one of the pi electrons in one of its tyrosyl
residues
