摘要
Heterodyne spectra of carbonyl sulfide have been obtained with saturation in a CO2 waveguide laser and without saturation with a diode laser. The absolute uncertainties of the measured positions lie between 10-4 and 7 × 10-6 cm-1. The CW submillimeter laser line of OCS at 378 μm has been assigned to the J = 65 → 64 transition in the 0220e state of 16O12C32S, with a pumping through the R(64) line of 0220e ← 0000, a Δ-Σ transition weakly allowed by the l-type resonance. © 1990.
