ResumoThe infrared vibration–rotation spectrum of the hydroxyl radical produced by the reaction of hydrogen atoms and ozone has been recorded. The intensity of individual lines in the fundamental sequence was found to be considerably weaker than was previously predicted. The intensity of lines in the fundamental sequence is compared with the intensity of the first overtone lines to obtain ratios of the vibrational transition probabilities. These ratios are used to remove the ambiguity of the OH dipole moment function associated with previously unknown intensities of the fundamental bands. A complete set of relative transition probabilities is given. An equilibrium flux calculation using atmospheric data is performed using the derived transition probabilities to obtain the vibrational distribution of OH at formation.
