Abstract
The infrared spectrum of the deuterated hydroxyl radical OD has been measured with a Fourier transform spectrometer between 1850 and 9000 cm−1. The source, a deuterium atom ozone diffusion flame, was designed to study the chemiluminescent excitation of the vibration-rotation energy levels of the OD radical. Twenty-one bands were observed, 6 bands in the Δv = 1 sequence, 9 bands in the Δv = 2 sequence, and 6 bands in the Δv = 3 sequence. A global nonlinear least-squares fit, utilizing the unique perturber approximation, of 2112 lines to 76 molecular parameters yielded a standard deviation of 0.007 cm−1 including 35 parameters for the previously unobserved v = 6-10 vibrational states.
