Lambda-doublet transfer and propensities in collisions of OH (X2Pi/i/, v = 2) with H2O

The present work is concerned with the changes in electronic parity (e/f states) during rotationally elastic and inelastic collisions. In the OH X2Pi(i) molecule considered in the study, the differences in the e/f state production in the photodissociation of both H2O and HONO1, in the H + O2 reaction, and in the initial-state-unselected H2-OH collisions, have been experimentally examined.
