The temperature variation of the rate coefficient for k(1) for CH3(+) + H2 yields CH5(+) + hv is computed treating the para and ortho forms of H2 separately, taking account of nuclear spin and using an accurate theory of the kinetics of association. The results are made absolute with the aid of the measurement at 13 K by Barlow et al. (1984). By combining this measurement with the CH5(+) vibrational frequencies obtained by Pople (1984) from a quantal study, it is deduced that the probability of the stabilizing radiative transition is 5400/s. The rate coefficients k(1) (T, para) and k(1) (T, ortho) are given at 13 K, 30 K, and 80 K. 23 references.
