Theoretical molecular photonics

Theoretical concepts of molecular photonics are presented. Features of the photophysical processes in molecular systems and the relationship between their probability and the electronic structures of the molecules are discussed. Possible mechanisms for the photochemical decomposition of electron-excited molecular systems with chemical bond cleavage are considered. The effect adiabatic photochemical reactions have on the probability of nonradiative conversion processes is shown. Dependences of spectral luminescence properties, the photochemical and radiation chemical stability of the molecular systems, and the efficiency of molecules of photostabilizers of polymers on their structure are interpreted. Areas of application are indicated for molecular photonics.
