Infrared and microwave high-resolution spectrum of the ν3 band of ozone

Abstract The vibration-rotation band ν 3 of ozone has been recorded with a high-resolution (0.012 cm −1 ) spectrometer, and microwave absorption spectra of ozone have been identified in the excited vibrational states (100) and (001). A strong Coriolis interaction has been observed. More than 1200 spectral lines have been identified in the ν 3 band, using a Watson-type Hamiltonian, including all the sextic centrifugal distortion terms. Band constants and an atlas listing line wavenumbers, intensities, and assignments are given, from 1007 to 1072 cm −1 . It is shown that transitions with high values of the quantum numbers K −1 (≥11) contribute to significant absorption.
