DATAFILE: CF2Cl2(CFC-12)_Gilbert(1974)_298K_63.4-121.2nm.txt
NAME: difluorodichloromethane (CFC-12)
AUTHOR(YEAR): Gilbert(1974)
T: 298K
λ: 63.4-121.2nm
BIBLIOGRAPHY: R. Gilbert, P. Sauvageau, and C. Sandorfy, "Vacuum ultraviolet absorption spectra of chlorofluoromethanes from 120 to 65 nm", J. Chem. Phys. 60, 4820-4824 (1974); DOI: 10.1063/1.1680987
COMMENTS: Absorption measurements using the helium (Hopfield) continuum for the 65-106-nm region and a hydrogen discharge tube for the 106-120-nm region as light sources and a vacuum spectrophotometer under 0.02 nm resolution

Extinction coefficients plotted in Fig. 2 and have been digitized converted to absorption cross sections (factor 3.8235×10-21)
