Comments: The photoabsorption cross sections of C3H6 isomers (cyclopropane and propylene) and C4H8 isomers (1-butene, iso-butene, 
cis-2-butene, and trans-2-butene) have been measured in the wavelength region from 300 Å to the ionization potential of each molecule 
(about 1200-1400 Å). The obtained photoabsorption cross sections show a maximum value at about 700-800 Å for each molecule.
