✦ Synopsis

Calculations LUustrnte a new physical process, Raman reflectton, wluch contributes to Raman scattermg by adsorbed molecules it IS Induced by the mteractlon between the vibratmg ion-core charges of adsorbed molecules and the electrons of the metal, this mteraction cz~uses energy transfer from the electron-hole pair to the oscdlatmg molecule Since the energy transferred equals the vibratIona energy, the photon emrtted by subsequent electron-hole recombmatlon 1s Raman sbfted, augmentmg the Raman intensity * A P Sloan Fellow and CamlUe and Henry Dreyfus Teacher-Scholar
