What is UV absorption cross-sections of a series of vinyl ethers about?

UV absorption cross-sections of six vinyl ethers (ethyl vinyl ether, 1,4-butanediol divinyl ether, isobutyl vinyl ether, cyclohexyl vinyl ether, 4-hydroxybutylvinyl ether and diethyleneglycol divinyl ether) have been determined in the gas phase between 190 and 230 nm at 303 ± 2 K and pressures up to the corresponding saturation vapor pressures. The main band maxima of the vinyl ethers are below 200 nm with values under 8 × 10 -17 cm 2 molecule -1 . The absorption vanishes above 225 nm with values of smaller than 1 × 10 -21 cm 2 molecule -1 . Weak, overlaying vibrational progressions with spacings of 1400 cm -1 are observed for the alkyl vinyl ethers and are less pronounced for vinyl ethers with an extra O atom. Shifts of the positions and intensities are discussed on the basis of the differences in the chemical structure of this series.
