The M61 skew 2-site fast exchange R1ρ model

This is the second model for 2-site fast exchange for on-resonance R1ρ-type data from Meiboom (1961). It is selected by setting the model to `M61 skew'. The equation for the exchange process is

R1ρ = R1ρ' + $\displaystyle {\frac{{p_{\textrm{A}}^2p_{\textrm{B}}\Delta\omega ^2\textrm{k}_{...
...{{\textrm{k}_{\textrm{ex}}^2 + p_{\textrm{A}}^2\Delta\omega ^2 + \omega_1 ^2}}}$. (11.74)

Care must be taken as this model appears to have infinite lines of solutions - pA and Δω are convoluted. Hence this model is disabled in the dispersion auto-analysis.
