Rotational excitation of OH by H2: a comparison between theory and experiment

Abstract
Comparison is made between close-coupling calculations of cross sections for the rotational excitation of OH by H2 and crossed-beam measurements. Good agreement is obtained for transitions within the 2 Pi 3/2 ladder, although discrepancies remain for inter-ladder (2 Pi 3/2-2 Pi 1/2) transitions. Differences with earlier coupled-states calculations by Schinke and Andresen (1984) are found and discussed.
