Rate of the reaction N2H++CO -> HCO++N2 and its significance for the interstellar chemistry of H2H+.
Abstract
The rate constant for the reaction N2H + + CO HCO + + N2 has been determined to be (8.79 l 0.13) x 10-10 cm3 s ' at 297 + 2 K with an estimated accuracy of +25 percent. The implications of this rate constant for the interstellar chemistry of N211 + are discussed. Estimates are made for the frequencies of the first rotational transitions in `5N14NH +, `4N'5NH +, and N2D +.
