The relative Raman intensities of ngr;(Mndash;L)A1gandEgmodes for somed0ML6anions ofOhsymmetry

摘要

The observation that unusual relative ngr;(Mndash;L) Raman intensities are associated with at62gconfiguration has prompted calculations ond0systems based on the hypothesis that charge transfer transitions to thet2gshell make a dominant contribution to the corresponding Raman intensities of these systems. A combination of Albrecht and Wolkensteinndash;Eliashevich models leads to the prediction of relative Raman intensities in good qualitative agreement with those observed experimentally.
