When Δ J =±1 collision-induced transitions in Π states of excited alkali diatomics are examined over a wide range of pressures several curious phenomena are observed. With the heavier rare gases we find that the ± propensities reverse as pressure

We report an unusual pressure dependence of the gas phase dynamics of alkali diatomics in 1Π excited states in their interactions with certain collision partners. This behavior consists of a change in the relative rates of the ΔJ=+1 and ΔJ=−1 co
