electron back-transfer
Thermal
inversion
of
excited-state
electron transfer
restoring the donor and acceptor in their
original
oxidation state
. In using this term one should also specify the resulting
electronic state
of the donor and acceptor. This term is preferred to
back electron-transfer
.
Notes:
It is recommended to use this term only for the process restoring the original
electronic state
of donor and acceptor.
Should the forward
electron transfer
lead to
charge separation
, electron back-transfer will result in
charge recombination
.
