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). It is selected by setting the model to `TSMFK01'. 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).
The equation is:
|R2eff = R2A0 + kAB - kAB||(11.35)|
The reference for this equation is:
