Price, D.M. Simpson Title: The absorption spectra of carbon dioxide and carbon oxysulphide in the vacuum ultra-violet Journal/Source: Proc. Roy. Soc. London, A169, 501-512, (1939); https://doi.org/10.1098/rspa.1939.0013 Data: table, diagram Energy/Wavelength range: ~ 150 - 260 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: < 3 Torr Phase: gas pH: Comments: The uv absorption spectrum of COS consists of two continua, with the lower energy continuum extending with maxima at 2080 and 2250 A, from 2550 down to ca. 1600 A. At very low pressures the first continuum resolves into several broad, diffuse bands involving a number of different electronic transitions. The second absorption region sets in at ca. 1550 A.
