Abstract: | The OD infrared spectrum, emitted in a flame of deuterium and oxygen, has been recorded for the first time in the 2-μm spectral range with a Fourier Transform spectrometer. A simultaneous fit of the ir 2-0, 3-1, 4-2, 5-3, 3-0, 4-1 vibration-rotation bands, of the uv data (0-0, 1-1, 2-2, 0–1 bands of the A2Σ+ → X2Π transition) and of the microwave data, gives accurate molecular constants for the ground-state vibrational levels up to v = 5. The classical “unique perturber approach” and the effective Hamiltonian of Brown for 2Π states, have been successively used for the reduction of the spectroscopic data. |
