This is the model for 2-site very-slow exchange model for time scales within range of microsecond to second time scale, where pApB, 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}.
