Tanaka Title: VUV-optical oscillator strength distributions of C2H6O and C3H8O isomers Journal/Source: J. Chem. Phys., 85, 4276-4279, (1986), DOI:http://dx.doi.org/10.1063/1.451800 Data: table, diagram Energy/Wavelength range: 30 - 105 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: 0.03 - 0.06 Torr Phase: gas pH: Comments: The photoabsorption cross sections of C2H6O isomers (ethyl alcohol and dimethyl ether) and C3H8O isomers (n-propyl alcohol, isopropyl alcohol, and ethyl methyl ether) have been measured in the wavelength region from 30 nm to the ionization potential of each molecule (about 120-130 nm). The obtained photoabsorption cross sections show a maximum value at about 70-80 nm for each molecule. The estimated total errors in the cross section values were about 15% in the wavelength region from 40 to 80 nm and about 20% in the other wavelength regions except near 100 nm.
