Abstract
With the use of a conventional high-resolution grating spectrometer and a Q-switched spin-flip Raman laser (SFRL), carbonyl sulphide ro-vibrational bands between 1852 and 1914 cm-1 have been measured and analysed. Rotational constants for seven bands have been calculated, including bands of the two isotopic species O13CS and OC34S occurring in natural abundance. The 1200←0000 band of OCS has been measured with an absolute accuracy of 0·002 cm-1 and so can be used for the calibration of the SFRL spectra in the 5·3 μm region.Keywords
