Waller, "Measurement of the rate coefficients for the bimolecular and termolecular charge trasfer reactions of [He.sub.2.sup.+] with Ne, Ar, [N.sub.2], CO, C[O.sub.2], and C[H.sub.4]," Journal of Chemical Physics, vol.
When NO is mixed with oxygen in a gaseous environment, nitrogen dioxide (N[O.sub.2]) is formed spontaneously by a termolecular mechanism (8).
The process leading to the result of the reaction [r.sub.3] can be approximated by a termolecular reaction, because it requires the quasisimultaneous collision of a P[degrees] radical freshly generated by a RO[degrees] fragment with another RO[degrees] fragment and before radicals P[degrees] undergo other scission or combination processes.
