Excited States

Excited States, Volume 2 is a collection of papers that deals with molecules in the excited states. The book describes the geometries of molecules in the excited electronic states. One paper describes the geometries of a diatomic molecule and of polyatomic molecules; it also discusses the determination of the many excited state geometries of molecules with two, three, or four atoms by techniques similar to diatomic spectroscopy. Another paper introduces an ordered theory related to excitons in pure and mixed molecular crystals. This paper also presents some experimental data such as those involving pure and neat crystals, very dilute isotopic mixed crystals, and medium dilute isotopic mixed crystals. The book also discusses the dynamics of primary photochemical processes including the classical theory of unimolecular reactions, the quantum theory of molecular reactions, and the theory of "nonchemical" radiationless processes. One paper also reviews the electron donor-acceptor complexes in their excited states. This book is suitable for nuclear physicists and researchers whose work involves molecular chemistry and solid state physics.
