The interaction between an excited electron and a large-radius exciton ( Wannier-Mott exciton) has been studied in the visible and ultra-violet frequency regions for a two-level system of a molecular solid. Using a self-consistent approach, it is shown that at low temperatures and when certain condi

An effective Hamiltonian is established which describes the excitation spectrum of independent quasiparticles arising from the coherent electron-exciton pairing in molecular solids of the charge-transfer type. This Hamiltonian is then used to study the interaction Of the quasiparticles with an exter
Theoretical arguments are presented indicating that the mtermolecular translational frequency in solid-state chargetransfer compIexes and dimers decreases upon electronic excitation\_ These arguments are used to explain some features of the spectrum of solid authracene-PMDA. \* Issued as NRCC No. 19
