Emission from vibrationally excited OH radicals is used to monitor the condition of the mesopause region and to trace the propagation of gravity waves through the nightglow layer. To extract information from the intensity of the emission, collisional energy transfer rate constants must be known or estimated for the temperature of the emitting layer. In addition to OH emission itself the energy from the reaction of hydrogen atoms with ozone can show up in CO2, affecting the altitude profile of the infrared emission from this important species.1 Laboratory studies have attempted to measure these rate constants for over forty years with varying degrees of success. In this work the rate constants for the interaction of vibrationally excited OH with the important atmospheric colliders, O2, N2, and O atoms will be assembled and critically evaluated. Where conflicting measurements are available a recommended value will be presented and the justification for excluding specific results outlined. Where no experimental values have been measured, best estimates will be provided based on the behavior of similar chemical systems. Estimates of the temperature dependence will be undertaken based on the limited laboratory data. The reasons and basis for the estimates will be outlined.
