AUTHOR(YEAR): Lacher(1950)
T: 298K
λ: 246-265nm
BIBLIOGRAPHY: J.R. Lacher, L.E. Hummel, E.F. Bohmfalk, and J.D. Park, "The near ultraviolet absorption spectra of some fluorinated derivatives of methane and ethylene", J. Am. Chem. Soc. 72, 5486-5489 (1950) DOI: 10.1021/ja01168a029
COMMENTS: Absorption measurements using a Beckman model DU quartz spectrophotometer

Absorption coefficients E = 10 k (atm, 298K)-1 cm-1 (base 10) depicted in Fig. 2 have been digitized and converted to absorption cross sections (conversion factor 9.35×10-21)
