Figure 47.
Schematic representation of the system and its interactions in the SHS theory of PCET. De (Dp) and Ae (Ap) are the electron (proton) donor and acceptor, respectively. Qe and Qp are the solvent collective coordinates associated with ET and PT, respectively. ξ denotes the overall set of solvent degrees of freedom. The energy terms in eqs 12.7 and 12.8 and the nonadiabatic coupling matrices d(ep) and G(ep) of eq 12.21 are depicted. The interactions between solute and solvent components are denoted using double-headed arrows.
