This has been a contradiction in my brain for some time.
If I want to rotate one nuclei (spin 1/2), with say an applied magnetic field B and RF pulse (at the appropriate larmor frequency), how does the spin actually rotate? I thought it can only take on discrete values of 1/2 or -1/2 corresponding to the parallel and anti-parallel directions (with respect to B). I am missing something here, and its killing me.
