Laser Raman Spectroscopy: Application to Solid State Photoreaction In Organic Crystals
Madhujya Gogoi
Abstract
Laser Raman Spectroscopy has been used to study the crystalline state photoreaction in organic materials. It is shown that in many such cases the reaction is mediated by lattice phonons. Phonon participation in solid state photoreaction occurs either through a strong exciton-phonon coupling and polar on formation or through softening a low frequency phonon mode in the electronic excited state of the crystal. Some dimerization and polymerization reactions are discussed to emphasize the thesis.
