Raman Study of Solid State Reactions in Polymeric Materials.

Abstract

This research accomplished under this grant focused on intermolecular interaction and reaction dynamics of several monomeric as well as polymeric systems. Specifically the following research areas were investigated: (1) Vibrational relaxation in organic solids. This study was necessitated from a need to formulate conditions under which a selective vibrational as well as a phonon excitation could be used to produce novel products by state selected chemistry; (2) Phonon spectroscopy of reactions in solids. This novel method was used to determine the mechanism of reactions and the role of phonons in reactivity of solids; (3) Raman phonon study of pharmaceutical solids in relation to their bioavailability. The method of Raman phonon spectroscopy was introduced as a convenient method to study various solid state forms of a given drug and their physical and chemical stabilities; (4) Structure and dynamics of the conducting complex: (Benzophenone)9 (KI)2 I7 CHCl3. Some preliminary work was done on this novel group of conducting materials; and (5) Phonon spectroscopy of polymeric alloy. This new method was introduced to determine the molecular homogeneities of polymer blends. (Author)
