Comments: Gas phase acetone and 3-pentanone absorption cross sections have been measured in shock-heated gases in the
wavelength range from 220 to 340 nm at temperatures between 300 and 1100 K.
The spectra are fitted to a parameterized Gaussian curve to allow for calculations of the cross sections as a
function of temperature and wavelength.
