DATAFILE: SO3_Suto(1987)_298K_144.6-159.8nm.txt
NAME: sulfur trioxide
FORMULA: SO3
AUTHOR(YEAR): Suto(1987)
T: 298K
λ: 144.6-159.8nm
BIBLIOGRAPHY: M. Suto, C. Ye, R. S. Ram, and L.C. Lee, "SO2 fluorescence from vacuum ultraviolet dissociative excitation of SO3", J. Phys. Chem. 91, 3262-3265 (1987); DOI: 10.1021/j100296a032
COMMENTS: Absorption measurements at medium resolution (0.2 nm) using synchrotron radiation as a light source

The "apparent" absorption cross sections plotted in Fig. 1a have been digitized

Because of the deterioration of SO3 by reactions with the sapphire or LiF windows, the broad bands shown in Figure 1a may be partly due to SO2 which also shows absorption structure in this wavelength region
