| Abstract: | Heterodyne frequency measurements between a frequency-stabilized 13CO2 reference laser and a tunable diode laser (either tuned or locked to various carbonyl sulfide absorption peaks) have been made on a number of 1000-0000 band transitions in the isotopic species of carbonyl sulfide: OC34S, O13CS, OC33S, 18OCS, and O13C34S. These OCS frequency measurements have been combined with existing microwave data and new sets of molecular constants obtained. These constants will be used later to form part of a frequency calibration compendium based on OCS. |
