DATAFILE: 1,2,3,4-C6H2Cl4_Scharping(1987)_298K_188.7-241.8nm.txt
NAME: 1,2,3,4-tetrachlorobenzene
FORMULA: 1,2,3,4-C6H2Cl4
AUTHOR(YEAR): Scharping(1987)
T: 298K
λ: 188.7-241.8nm
BIBLIOGRAPHY: H. Scharping, C. Zetzsch, and H. A. Dessouki, "The UV absorption spectra of the trichlorobenzenes and the higher chlorinated benzenes in the gas-phase and in n-hexane solution", J. Mol. Spectrosc. 123, 382-391 (1987); DOI: 10.1016/0022-2852(87)90286-4
COMMENTS: Absorption measurements at a resolution of 50 cm-1 (≈ 0.18-0.30 nm) using a gas saturation method

The absorption curve depicted in Fig. 2 (logarithmic scaling for σ from 5×10-18 to 5×10-16) has been digitized

The text however says: "because of the lack of vapor pressure data, only relative absorption cross sections can be presented"
