This is the relaxation dispersion model for 2-site exchange on all times scales (with the constraint that p_A >> p_B $p_A \gg p_B$ named after Ishima and Torchia (1999). The reference This model is:labelled as '''IT99''' in relax.

== Parameters == The IT99 model has the parameters {$R_2^0$, $...$, $p_A$, $\Delta\omega$, $k_{ex}$}. == Reference == The reference for the IT99 model is: * Ishima, R. and Torchia, D. (1999).
