The TSMFK01 2-site CPMG model

This is the model for 2-site very-slow exchange model for time scales within range of microsecond to second time scale, where
*p*_{A} *p*_{B}, 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:

R_{2eff} = R_{2A}^{0} + k_{AB} - k_{AB} |
(11.35) |

The reference for this equation is:
