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.
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.
For this model, the equations from Korzhnev05 have been used.
The R1ρ value for state A magnetisation is defined as
[math]
\begin{equation}
\mathrm{R}_{1\rho} = - \frac{1}{T_\textrm{relax}} \cdot \ln \left( M_0^T \cdot e^{R \cdot T_\textrm{relax}} \cdot M_0 \right),
\end{equation}
