DATAFILE: C3O2,O=C=C=C=O_Roebber(1971)_195K_168.3-183.0nm.txt
NAME: carbon suboxide, tricarbon dioxide
FORMULA: C3O2,O=C=C=C=O
AUTHOR(YEAR): Roebber(1971)
T: 195K
λ: 168.3-183.0nm
BIBLIOGRAPHY: J.L. Roebber, "Vacuum-ultraviolet absorption spectrum of carbon suboxide. II. The effect of low temperature and the effect of high pressure of an inert gas on the 1780-Å band", J. Chem. Phys. 54, 4001-4013 (1971); DOI: 10.1063/1.1675457
COMMENTS: The spectrum was recorded with a 1-m vacuum monochromator provided with a 600 groves/mm MgF2-coated grating and a dc cold cathode hydrogen discharge lamp; instrumental bandwidth ~0.1 nm

Absorption coefficients k (atm, 273K)-1 cm-1 (base e) vs. wavenumbes plotted in Fig. 1 have been digitized and converted to absorption cross sections (conversion factor 3.72×10-20) vs. wavelength
