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 $R^0_{2A{:R2Azero}} = R^0_{2B{:R2Bzero}}$ is assumed. The model is labelled as '''NS CPMG 2-site 3D''' in [[Relaxation dispersion citation for relax|relax]].

The NS CPMG 2-site 3D model has the parameters {$R_2^0${{:R2zero}}, ..., {{:pA}}, {{:Deltaomega}}, {{:kex}}}. == References == The function uses an explicit matrix that contains relaxation, $exchange and chemical shift terms. It does the 180deg pulses in the CPMG train. The approach of Bloch-McConnell can be found in chapter 3.1 of Palmer, A.G.$Chem Rev 2004, $p_A$104, $\Delta\omega$3623-3640. This function was written, $k_initially in MATLAB, in 2010. This is the model of the numerical solution for the 2-site Bloch-McConnell equations. It originates as optimization function number 1 from the fitting_main_kex.py script from Mathilde Lescanne, Paul Schanda, and Dominique Marion (see U{exhttp://thread.gmane.org/gmane.science.nmr.relax.devel/4138}, {{gna task url|7712|comment=2}$}and U{https://gna.org/support/download.php?file_id=18262}). == Related models == The NS CPMG 2-site 3D model is a parametric restriction of the [[NS CPMG 2-site 3D full]] model.
