Lin Title: Extinction Coefficients of Chlorine Monoxide and Chlorine Heptoxide Journal/Source: J. Chem. Eng. Data, 21, 411-413, (1976); DOI: 10.1021/je60071a030 Data: table, diagram Energy/Wavelength range: 180 - 640 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: 1 - 165 Torr Phase: gas pH: Comments: The uv-vis extinction coefficients of Cl2O and Cl2O7 were measured from 180 to 800 nm. for Cl2O no absorption was recorded for wavelengths greater than 650 nm.
