Abstract
The Fourier Transform spectra at isotopically enriched carbon disulfide have been obtained with a resolution of $0.01 cm^{-1}$ at the Kitt Peak National $Observatory.^{*}$ The ($\nu_{1} + \nu_{3}$) combination binds in the region $2100-225O cm^{-1}$ of several isotopic species particularly ${^{12}}C{^{32}}S{^{34}}S, {^{12}}C{^{32}}S{^{33}}S, {^{12}}C^{32}S_{2}$ and ${^{13}}C{^{32}}S_{2}$ have been reinvestigated. Due to the better resolution in the present studies, closely spaced lines could be resolved. Leading to better determined molecular constants. Two new bend systems $02^{0} 1+ 0000$ and $03^{1}1 \leftarrow 01^{1}0$ of $^{12}C^{32}S^{34}S$ have also been identified and analyzed. The $\ell$-type doubling in the $\Pi -\Pi$ band was found to be resolved for lines with $J > 13$, and the l-type doubling constants for the $0l^{1}0$ and $03^{1}1$ states of ${^{1}2}C^{32}S^{34}S$ have been obtained.
