Abstract

Two double-resonance spectroscopic schemes incorporating vibrational overtone excitation have been implemented to investigate the intramolecular energy transfer and unimolecular dissociation dynamics of several small molecules. In the first case, an infrared-optical double-resonance scheme simplifies the room-temperature vibrational overtone spectra of hydrogen peroxide and hydroxylamine and prepares highly excited reactant molecules in single rotational states above their respective dissociation thresholds.
