larmor frequence - DAVID FORTIN MENKE - 08-26-2015 06:06 AM
Hi everybody !
Can you explain me this:
if wo = gamma.Bo and if wo = 2(pi)fo why fo = (only) gamma.Bo too ???? i don't understand why it isn't: fo = gamma.Bo/2(pi) ?
Thanks for any answer.

The gyromagnetic ratio (gamma) can be defined in terms of either angular frequencies with units (radians/Tesla) or "regular" frequencies where it has units of MHz/Tesla. I have chosen the latter. The two differ by a factor of 2 pi.
See the following link if you are still confused.
