Comments: The absorption cross sections at the chemical-iodine-laser frequency for methane and carbon dioxide in an 
atmosphere of dry air were determined with a photoacoustic cell to be (8 ± 2) × 10-24 and (5.4 ± 0.4) × 10-25 cm2, respectively.
A multipass absorption cell and a Fourier-transform spectrometer were used to obtain a cyclopropane absorption cross section 
of (3.47 ± 0.02) × 10-24 cm2 at 14076 cm-1.
