The relaxation dispersion model for the numeric solution (NS) to the Bloch-McConnell equations for SQ CPMG-type data using 3D magnetisation vectors whereby the simplification R2A0 = R2B0 is assumed. The model is labelled as NS CPMG 2-site 3D in relax.
Parameters
The NS CPMG 2-site 3D model has the parameters {R20, ..., pA, Δω, kex}.
