Scientific paper

High- and medium-resolution ultraviolet spectra from the Space Telescope Imaging Spectrograph (STIS) and the Goddard High Resolution Spectrograph (GHRS) were used to study the diatomic molecule CS through the C-X(0,0) band at 1401 Å. The band was modeled to verify profile shape. The rest wavelength of the C-X band is refined to a value of 1400.88 Å and a 3σ lower limit is set on the oscillator strength at 0.14 based on equivalent width upper limits of the A-X(0,0) CS Band at 2577 Å. The strength of the 1401 Å band is compared to other interstellar parameters and implications for CS formation and destruction are briefly discussed.
