63. +, ;,\CB = 4 in principle predict a faster quenching rate for the latter pair. Since we observe similar forward rates, . however, we have chosen to forgo this analysis in discussing ASCpFurthermore, the respective ET products, MP'~/QU'~ and MP3~/QH' would favor a larger k-4p for the pair based on MP3~/Qo'~ Coulombic repulsion. Our observation of fewer free ions in this case suggests that XVP may not be dominant in determining the relative yields,

65. The MP+/UQo'~ curve indicates overwhelmingly favorable FCWD(t>.\) for BET, and the survival of a reasonable population of free ions in this instance, and is testimony to a small value of V connected to 3(MP44Y UQo') -'(MP/UQ,)) charge recombination.
66. Based on exchange interaction energy considerations, BET to the neutral ground state involves the spin forbidden triplet to singlet pathway, rather than intersystem crossing, to the singlet state, prior to charge recombination.
