Description
Infrared emission has been observed from CH3F collisionally excited by hot hydrogen atoms produced in the photolysis of H2S at 193 nm. The time-dependent emission at 2.5 (ν1+ν3, ν4+ν3), 3.3 (ν1, ν4), and 9.6 μm (ν3) has been analyzed, and both T-V and V--V energy exchange processes are observed. Relative populations of molecules excited into the ν3 and ν1, ν4 modes were determined; the population in the C--H stretching modes (ν1, ν4) is much lower than predicted by simple impulsive models of the collision process
