The Meiboom 1961 2-site on-resonance fast exchange relaxation dispersion model for R1rho-type data. This model is labelled as M61 in relax.

Equation

[math] \mathrm{R}_{1\rho}= \mathrm{R}_{1\rho}{´} + \frac{\Phi_\textrm{ex} \textrm{k}_\textrm{ex}}{\textrm{k}_\textrm{ex}^2 + \omega_\textrm{e}^2} [/math]

Parameters

The M61 model has the parameters {R', ..., Φex, kex}.
