We report a dynamics study of both reactive and non-reactive O + OH(v' j') collisions under local thermodynamic disequilibrium. Besides the total rate constant for temperatures over the range 110 less than or equal to T/K less than or equal to 450, vibrationally specific ones are reported for quantum numbers v' less than or equal to 9. Unknown thus far, such kinetic parameters may be of relevance in modelling the OH nightglow in the middle atmosphere. (C) 2004 Elsevier B.V. All rights reserved.
