Microwave absorption spectroscopy in the ν3states of OCS and N2O through energy transfer from N2*

Abstract

The rotational spectrum of the nu ₃ states of OCS and N₂O, whose levels lie near 2000 cm^-1, has been observed through a vibrational energy transfer from active nitrogen. The frequencies of many transitions between 48 GHz and 158 GHz have been measured; a determination of the rotational and centrifugal distortion constants of these states has been derived.
