Pyridine-cyanoanthracene bonded exciplex

Abstract

Exiplexes are a special kind of molecular complexes, which exist only due to a weak bond in an excited state. The theoretical description of these complexes requires the usage of multiconfigurational theory (CASSCF or RASSCF) followed by second order of perturbation theory. Formation of exiplex complex from pyridine and cyano-anthracene has been studied.
