OH+ Formation in the Low-temperature O+(S-4) + H-2 Reaction
Original language description
Formation of OH+ in collisions of ground-state O+(S-4) ions with normal H-2 has been studied using a variable temperature 22-pole RF ion trap. From 300 to 30 K the measured reaction rate coefficient is temperature-independent, with a small decrease toward 15 K. The recent wave packet calculation predicts a slightly steeper temperature dependence. The rate coefficients at 300 and 15 K are almost the same, (1.4 +/- 0.3) x 10(-9) cm(3) s(-1) and (1.3 +/- 0.3) x 10(-9) cm(3) s(-1), respectively. The influence of traces of the two metastable ions, O+(D-2) and O+(P-2), has been examined by monitoring the H+ products of their reactions with H-2, as well as by chemically probing them with N-2 reactant gas.
