RFresonance

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.
