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).
