Abstract

The method of infrared microwave sideband laser spectroscopy developed by G. Magerl, et al. (ibid, vol.18, p.1214-20, 1982) for application in the 9-11-μm region with a CO₂ laser has been extended to application in the 5-6-μm region with a CO laser. The experimental details, performance of the system, and typical spectra are described. Frequency measurements of spectra in the 01¹1←00⁰0 band of ¹⁴N₂ ¹⁶O and the 20⁰←00⁰0 band of ¹⁶O¹²C³²S are compared to the results of previous precise measurements by heterodyne techniques to show that the accuracy is limited mainly by the resettability of the CO laser frequency
