Comments: The NF3 gas-phase UV absorption spectrum, sigma(lambda,T), was measured at 16 wavelengths 
between 184.95 and 250 nm at temperatures between 212 and 296 K. A significant spectrum temperature 
dependence was observed in the wavelength region most relevant to atmospheric photolysis (200-220 nm) with 
a decrease in sigma(210 nm,T) of ~45% between 296 and 212 K.
