More Sub-Doppler Heterodyne Frequency Measurements on OCS between 56 and 63 THz

By using tunable microwave sidebands added to CO-laser lines, we have made more sub-Doppler heterodyne frequency measurements on OCS. Three new rotational transitions have been measured for each of three absorption bands, 10(0)0-00(0)0, 02(0)1-00(0)0, and 03(1)1-01(1)0. The absolute uncertainties of the measurements are on the order of +/-25 kHz. New calibration tables are given for the region 1860-1925 and 2020-2085 cm(-1) based on the most recent OCS measurements.
