No Rex
The relaxation dispersion model for no chemical exchange. This if for all SQ CPMG-type data, MMQ CPMG-type data, and R1rho-type data. This model is labelled as No Rex in relax.
Parameters
The No Rex model has the parameter R20 or R1ρ' depending on the data type.
Equation for No Exchange in CPMG
[math] R_{2,\textrm{eff}} = R_2_0 [/math]
