✦ Synopsis

A computational result is presented for naphthdene which suggests that the conformation of the triplet evcimer is significantly different from a sandwich-pair geometry favored by the singlet excimer. A major consequence of the non-sandwich-pair geometry of the triplet excimer is a breakdown of the o--R separation which leads to an increased Tr -r So radiative transition probability for the excimer as compared to the corresponding monomer.
