Paper Abstract

Molecules that absorb 10.5-μm CO2 laser radiation are important as candidates for laser isotope separation and as possible saturable absorbers, passive mode lockers, and subjects for various non-linear optics experiments. Two such molecules are SF6 and OsO4, which have dense and complex absorption features that were not resolved until the development of tuna-ble diode lasers (resolution <10-5 cm-1). The spectra of these two compounds have been ex-amined in the region 940-970 cm-1 and will be discussed, with special attention to calibra-tion techniques. Full assignments and analyses of the bands have been carried out, isotope shifts measured, and the molecular constants determined. Application of these results to the analysis of non-linear optics experiments will be discussed.
