In my understanding, when a nuclei absorbes a photon with the right freq it changes its spin...
now, if this atom is in a magnetic field B on the Z direction, its magnetization vector is precessing around the Z direction, and after absorbing a photon it changes its angle relative to the Z axis.
with enough photons we can make the magnetization vectore exist only on the X-Y plane, and with even more photons it is possible to make the magnetization vector point to the -Z direction.
am i right?
if my view of the process is right, i have trouble seeing why would there be frequency involved... it seems pretty contineus to me.
and I've seen the use of rotating axis in some explanations... why would we need these? do the photons have circular polarization?
im a bit confused...
