| Abstract: | An uncollimated molecular beam (free jet) of CO and O2 molecules incident on a polycrystalline Pt surface at 775 K in vacuo produces vibrationally hot CO2 molecules at a density sufficient for infrared emission spectrometry. Analysis of spectra at a resolution of 0.1 cm?1 clearly shows that nascent product molecules have much more internal excitation than would be the case for equilibrium at the surface temperature. |
