A STUDY OF HOCO RESONANCES IN THE OH-]CO2+H REACTION(CO)

Quasibound states of the HOCO intermediate in the reaction OH+CO-->H+C O2 are studied by means of the stabilization method. A reduced-dimensi onality model is used. The calculated resonance positions and lifetime s agree well with previous quantum scattering calculations. Most of th e quasibound states can be assigned approximately to a vibrational exc itation in the higher frequency OH vibration and different progression s in the HO-CO stretching mode. Some interesting mode-specific effects in the dynamics of the unimolecular decay are predicted.
