Abstract
“The pure rotational spectrum and the vibrational spectrum of $CS_{2}$ vapour have been photographed with a 21 ft grating. Rotational lines up to $J=94$ have been measured and values of the constants $B_{o}$ and $D_{o}$ have been determined. As is well known, the vibrational Raman spectrum of $CS_{2}$, similar to that of $CO_{2}$, consists of the Fermi diad $v_{1}, 2v_{2}$ with some additional ``hot bands. In $CS_{2}$, the resonance is not as strong as in $CO_{2}$ and the $v_{1}$ Q branch is by far the most intense line observed. In the present research, a total of 14 sharp Q branches were photographed in the region of the diad ($630-820 cm^{-1}$). Also the rotational structure of the $v_{1}$ vibrational band was observed and analyzed. These results, together with published data on the infrared spectrum, are used to determine $B_{e}$ and the vibrational constants $\omega_{i}$ and $x_{1{k}}$.”““
