Gibson, N.S. Bayliss Title: Variation with Temperature of the Continuous Absorption Spectrum of Diatomic Molecules: Part I. Experimental, The Absorption Spectrum of Chlorine Journal/Source: Phys. Rev., 44, 188-192, (1933); DOI: 10.1103/PhysRev.44.188 Data: table, diagram Energy/Wavelength range: 5.6 - 25.2 nm Resolution: Temperature: 291 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: A photographic method was used to investigate the continuous absorption spectrum of chlorine at 18°, 168°, 281°, 426°, 580° and 765°C. The effect of increasing the temperature is to decrease the absorption coefficient at the maximum, and to broaden the region of continuous absorption.
