.. index:: RFresonance
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.
