Phys., 13, 15318-15325, (2011); DOI: 10.1039/C1CP21337G Data: table, diagram Energy/Wavelength range: 509 - 570 nm Resolution: 0.05 nm Temperature: 197 K; 233 K, 273 K, 298 K Temperature dependence: yes Pressure/Concentration: Phase: gas pH: Comments: The absorption spectrum of molecular chlorine has been measured, in the wavelength range 509-570 nm, using cavity enhanced absorption spectroscopy. Absolute absorption cross sections were obtained by simultaneous measurement of the UV spectrum to obtain the Cl2 concentration. These are the first temperature dependent measurements of the Cl2 absorption cross sections in this region which are vibronically resolved. Laboratory measurements were conducted at four temperatures (298, 273, 233, and 197 K). Author to whom correspondence should be addressed: (e-mail address):
