The Carver and Richards 1972 2-site relaxation dispersion model for [[SQ CPMG-type data]] for most time scales whereby the simplification R20A = R20B is assumed. It This is labelled as '''CR72''' in relax. == Parameters == The CR72 model has the parameters {R20$R_2^0$, $...$, pA$p_A$, ∆ω$\Delta\omega$, kex$k_{ex}$}. == Reference == The reference for the CR72 model is: * Carver, J. and Richards, R. (1972). General 2-site solution for chemical exchange produced dependence of T2 upon Carr-Purcell pulse separation. ''J. Magn. Reson.'', '''6'''(1), 89-105.
