The rate coefficient for the charge transfer reaction C+2po + H → C 3p+ H+ is calculated with the introduction of the radial coupling between the two 3π states arising from both asymptotic atomic states. the derived rate coefficient at a temperature of 104K is 2 10−15 cm3s−1 which is two orders of magnitude larger than the value previously estimated by Butler and Dalgarno (1980) from a weak spin orbit coupling between the 3Σ− and 3Σ+ molecular states of CH+.
