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.
