| Abstract: | We consider the dependence of the exchange interaction in electron transfer processes on the intersite vibrational modes. We assume, in particular, that high-frequency intramolecular modes of proteins may play this role in biological processes. We compare our model with that for tunneling through a time dependent barrier and with other works which considered the dependence of the exchange interaction on the nuclear coordinates.Work partially supported by the Brazilian Agency CNPq and by the NSF (Grant PCM-8406049)On leave of absence from Institute de Física e Química de São Carlos, Universidade de São Paulo, 13560, São Carlos, SP, BrazilOn leave of absence from Departamento de Física, Universidade Federal de Pernambuco, 50000, Recife, Pe, BrazilContribution No. 7325 |
