PERMANENT ELECTRIC DIPOLE MOMENT MEASUREMENTS OF TRANSITION METAL OXIDES

Author Institution: Department of Chemistry, Arizona State UniversityThe diverse and practically important chemical properties of transition metals have made them the focus of theoretical and experimental endeavors. Insight into the chemical properties of transition metals can be gained from an understanding of individual gas-phase transition metal containing molecules. The most relevant data for the elucidation of chemical bonding in these compounds are the permanent electric dipole moment and the magnetic hyperfine interactions. Because of the inherently transitory nature of these high temperature compounds there has historically been a lack of experimental information of this type. With the use of intermodulated fluorescence (IMF)-Stark spectroscopy it has been possible to determine permanent electric dipole moments for the ground and excited electronic states of CuO, CuS, FeO, and CrO. The results of these high resolution spectroscopic studies and comparison with theoretical and semi-emperical models will be presented
