Tanaka Title: VUV-optical oscillator strength distributions of C2H6O and C3H8O isomers Journal/Source: J. Chem. Phys., 85, 4276-4279, (1986); DOI: 10.1063/1.451800 Data: table, diagram Energy/Wavelength range: 30 - 125 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. Especially in the cases of dimethyl ether and ethyl methyl ether vibrational structures of the cross section are observed in the wavelength region from 70 to 100 nm.
