NS R1rho 3-site linear

The 3-site exchange relaxation dispersion model for the numeric solution (NS) to the Bloch-McConnell equations for R1rho-type data, linearised with k_AC = k_CA = 0. This model is labelled as NS R1rho 3-site linear in relax.

Parameters

The NS R1rho 3-site linear model has the parameters {R_1ρ', ..., p_A, p_B, Δω_AB, Δω_BC, k_ex^AB, k_ex^BC}.
