Abstract
Quantum-chemical calculations have been carried out for molecules of the bifluorophores naphthalene-(CH2)n-anthracene. The electronic structure and molecular-orbital nature of the excited electronic states of the molecules was analyzed and the rate constants of the photophysical processes were estimated. It is shown that for molecules with n=1, 2, 3 the transfer of excitation energy from the donor fragment (naphthalene) to the acceptor (anthracene) is completely equivalent to internal conversion.
