W. Nibler has been on Sabbatical leave from Department of Chemistry, Oregon State University, Carvallis, Oregon, 97331. en_US dc.description Author Institution: Department of Chemistry, State University of New York en_US dc.description.abstract Phonon bands in mixed crystals of p-dihalobenzene series $(p-C_{6}H_{4}XY$, with $X$ and $Y = Cl, Br, I)$ have been studied by laser Raman spectroscopy. The method of successive perturbation (increase in the halogen size of the impurity) has been used to develop a criterion for the formation of localized phonon states in these organic alloys. The relative manifestations of the dynamic disorder (mass and force constant defects) and the static disorder (structural imperfections) are investigated by studying the phonon bands of a particular organic alloy at various compositions. The efficacy of isotopic substitution on the chemical impurity is examined in relation to isolating the role of the mass defect. en_US dc.format.extent 93549 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title EFFECT OF SUCCESSIVE PERTURBATION ON PHONON BANDS IN AN ORGANIC ALLOY en_US dc.type article en_US
