What Does Omega 1 Represent in NMR Experiments?

[peterjaybee]

Hello,

The nutation frequency in NMR is given as

$$\omega_{1} = - \gamma B_{1}$$
Here gamma is the gyromagnetic ratio and B1 the radio frequency field.

My problem is that this is all well and good, but what does omega 1 actually represent in an NMR experiment? What is its physical meaning?

Regards,

Peter

It is the frequncy of the magnetization at resonance condition in rotating co ordinate system.
