DATAFILE: CCl3CHO_LucazeauSandorfy(1970)_298K_117.1-181.6nm.txt
NAME: trichloroacetaldehyde, chloral
FORMULA: CCl3CHO
AUTHOR(YEAR): LucazeauSandorfy(1970)
T: 298K
λ: 117.1-181.6nm
BIBLIOGRAPHY: G. Lucazeau and C. Sandorfy, "The far-ultraviolet spectra of some simple aldehydes", J. Mol. Spectrosc. 35, 214-231 (1970); DOI: 10.1016/0022-2852(70)90199-2
COMMENTS: Absorption measurements using a hydrogen discharge tube as the light source and a vacuum spectrophotometer under 0.02 nm resolution

Molar extinction coefficients vs. wavenumbers plotted in Fig. 6 have been digitized and converted to absorption cross sections (conversion factor 3.8235×10-21) vs. wavelengths
