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 R' depending on the data type.

Equation for No Exchange in CPMG

[math] R_{2,\textrm{eff}} = R_2^0 [/math]

Equation for No Exchange in R1rho

[math] \mathrm{R}_{1\rho}= \mathrm{R}_1\cos^2\theta + \mathrm{R}_{1\rho}{´} \cdot \sin^2\theta [/math]

Reference

These is no reference for the No Rex model.
