NS R1rho 2-site
The relaxation dispersion model for the numeric solution (NS) to the Bloch-McConnell equations for 2-site exchange for R1rho-type data. This model is labelled as NS R1rho 2-site in relax.
Contents
Equation
This is the numerical model for 2-site exchange using 3D magnetisation vectors. It is selected by setting the model to NS R1rho 2-site. The simple constraint {$\pA > \pB$} is used to halve the optimisation space, as both sides of the limit are mirror image spaces.
Parameters
The NS R1rho 2-site model has the parameters {$R_{1\rho}'$, $...$, $p_A$, $\Delta\omega$, $k_{ex}$}.
