This is the model for 2-site very-slow exchange model for time scales within range of microsecond to second time scale, where pA ≫ pB, and named after Tollinger et al. (2001). This model is labelled as TSMFK01 in relax. A particularly interesting feature of the dispersion curves is the damped oscillations, which occur at low CPMG field strengths, and is solely a function of the chemical shift difference between the two sites (i.e., independent of the rate of exchange).

Parameters

The TSMFK01 model has the parameters {R2A0, ..., Δω, kAB}.

The reference for the TSMFK01 model is:
