Intro

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 {$R_{1\rho}'$, $...$, $\Phi_{ex}$, $k_{ex}$}.

Reference

The reference for the M61 model is:

  • Meiboom, S. (1961). Nuclear magnetic resonance study of proton transfer in water. J. Chem. Phys., 34(2), 375-388. (10.1063/1.1700960).

Related models

The DPL94 model is an extension of the M61 model for off-resonance data.
