MD-PMM kinetic profiles for the primary charge separation process for pathway SP long-range as obtained by means of the distribution of the time intervals required for the first ET to occur (TE=0.0) scaled by the adiabatic fraction,χ(black circles). For the ChlD1-PheoD1pairand for the PD1-PD2-PheoD1trimer. Red lines: biexponential fitting of the corresponding distributions providing the following time constants reported in the figure:τChl,1=fs andτChl,2=ps for the ChlD1channel andτLR,1=ps andτLR,2=ns (the numbers in parenthesis are the populations associated to the corresponding time constants). The grey lines indicate the time distributions corresponding to a change of ±20 % in the adiabatic fractionχand that were used to estimate the uncertainty on the time constants.
