Vibrationally Excited CO2 from the Reaction of O Atoms and Adsorbed CO on Platinum

摘要

Highly excited CO2 is produced by the reation O + CO sub ads over platinum yields CO*. Its infrared emission spectrum indicates that more than half of the 4.1 eV exoergicity appears in asymmetric stretch vibration in a distribution peaked roughly at level (009). CO2* is destroyed by O atoms at high pressure rho approx. = 10 mTorr). The reaction dynamics and applications are discussed.
