Heterodyne frequency measurements on the 116-μm band of OCS: new frequency/wavelength calibration tables for 116- and 58-μm OCS bands

Heterodyne difference frequency measurements between a (13)CO(2) laser and a diode laser tuned (and in most cases locked) to the peaks of OCS absorption lines have been used to improve frequency calibration tables in the 860-cm(-1) region by factors of 20-50. Measurements have been made on the vibrational transitions 10(0)0-00(0)0, 11(1)0-01(1)0, and 20(0)0-10(0)0 for OCS. The measurements on the 10(0)0-00(0)0 and 20(0)0-10(0)0 transitions are also used to provide frequency calibration tables for the 20(0)0-00(0)0 band of OCS near 1700 cm(-1).
