~~= Intro =~~

The relaxation dispersion model for the numeric solution (NS) to the Bloch-McConnell equations for [[SQ CPMG-type data]] using complex conjugate matrices. The model is labelled as '''NS CPMG 2-site star full''' in [[Relaxation dispersion citation for relax|relax]].

== Parameters ==

The NS CPMG 2-site star full model has the parameters {~~$R_~~{2A{:R2Azero}}~~^0$~~, ~~$R_~~{2B{:R2Bzero}}~~^0$~~, $...$, ~~$p_A$~~{{:pA}}, ~~$\Delta\omega$~~{{:Deltaomega}}, ~~$k_~~{ex{:kex}}$}. == Code == The library code: {{relax url|path=lib/dispersion/ns_cpmg_2site_star.py}}

== References ==

NThe function uses an explicit matrix that contains relaxation, exchange and chemical shift terms. It does the 180 deg pulses in the CPMG train with conjugate complex matrices. The approach of Bloch-McConnell can be found in chapter 3.1 of Palmer, A. G. 2004 ''Chem. Rev.'', '''104''', 3623-3640. This function was written, initially in MATLAB, in 2010. The code was submitted on this [http:/A/thread.gmane.org/gmane.science.nmr.relax.devel/4132 mailing list thread] by Paul Schanda.
