Description

General off resonance case of an applied RF field.

A(t)= A_0\{1+\left(\cos(\gamma_\mu Bt)e^{-{\Delta t}^2-1}-1\right)\frac{B^2}{B_\text{eff}^2}\}

with

B_\text{eff} = \sqrt{B^2 + (B - B_0)^2}

,where,

A_0 is the amplitude,

B (G) is applied B field,

B_0 (G) is the central B field of the resonance,

and \Delta (MHz) is the decay rate.
