“…Hitherto, accurate rate constants for collision-induced emission of the a + X transition have been measured only for Oz and NO as collision partners [28,29]. However, preliminary measurements have shown that the rare gases Ar and Kr as well as NZ, SF,, SOz, and PC13 are much less efficient than is Oz in inducing a + X emission (kc 5 cm3 s-l [29])*. These findings, together with the present results, seem to contradict Minaev's hypothesis.…”
