✦ Synopsis

The infrared spectrum of the deuterated hydroxyl radical OD has been measured with a Fourier transform spectrometer between 1850 and (9000 \mathrm{~cm}^{-1}). The source, a deuterium atom ozone diffusion flame, was designed to study the chemilumineseent excitation of the vibration-rotation energy levels of the OD radical. Twenty-one bands were observed, 6 bands in the (\Delta v=1) sequence. 9 bands in the (\Delta v=2) sequence. and 6 bands in the (\Delta v=3) sequence. A global nonlinear leastsquares fit, utilizing the unique perturber approximation, of 2112 lines to 76 molecular parameters yielded a standard deviation of (0.007 \mathrm{~cm}^{-1}) including 35 parameters for the previously unobserved (v=6-10) vibrational states. 0,1994 Academic Press.
