ZFdipole

Description

ZF PCR signal from interaction with a single dipole.

\[A(t)=\frac{A_0}{6}\left(1+e^{-\lambda t}\left(\cos(g_\mu B_\text{D} t)+ 2\cos(\frac{3}{2}g_\mu B_\text{D} t)+2\cos(\frac{1}{2}g_\mu B_\text{D} t)\right)\right)\]

where,

\(\lambda\) (MHz) is the relaxation rate,

\(A_0\) is the amplitude,

and \(B_\text{D}\) (G) is the dipolar field.
