Abstract

Previous investigations have shown that infrared multiphoton excited polyatomic molecules (re)distribute the absorbed infrared energy among their different vibrational degrees of freedom. Multiphoton excitation of an infrared mode therefore alters the excitation of other modes, including Raman-active modes. From the change in Raman signals one can thus obtain information on the intramolecular vibrational distribution produced by infrared multiphoton excitation.
