State-to-state rotational energy transfer in OH (A 2?+, ??=1)

Abstract

State-to-state rotational energy transfer (RET) coefficients for thermal collisions of OH (A2Σ+, υ′=1) with He, Ar, N2, CO2, and H2O at 300K were determined from time-resolved laser-induced fluorescence (LIF) measurements. The RET coefficients are very similar in both qualitative behaviour and absolute magnitude to those measured previously for OH (A2Σ+, υ′=0).
