Photo-CIDNP studies of intramolecular charge transfer reactions in rigid donor-spacer- acceptor complexes
نویسندگان
چکیده
The photoinduced intramolecular electron transfer in five donor-bridge-acceptor systems is studied by analysing the field dependence of chemically induced dynamic nuclear polarisation. The exchange interaction, J, in the charge separated state of these complexes is determined as function spacer length. J has positive sign and shows an exponential decrease with increasing bridge length. By comparison with DFT calculations it is shown that through-bond contributions to J are the dominant factor.
