    Moderation of photochemically generated hot hydrogen atoms
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1978, 74 (07), 1978) Oldershaw, Geoffrey A.; Smith, Alan
    Hot hydrogen atoms generated by photolysis of gaseous HI react with OCS to produce CO by eqn (1). H*+ OCS → CO + SH (1). This reaction has been used to examine the moderation of the hot atoms by added C2H6, C3H8, n-C4H10, CH3F, C2F6, C3F8 and SF6. In each case the value of the energy-loss parameter α, relative to that for argon, is greater than that calculated assuming elastic collisions between the hot atom and moderator. Alkanes are the most efficient of the moderators examined, with relatively minor differences in α for C2H6, C3H8 and n-C4H10.
