Ultraviolet absorption coefficients of CO₂, CO, O₂, H₂O, N₂O, NH₃, NO, SO₂, and CH₄between 1850 and 4000 A

The ultraviolet absorption coefficients have been, determined for CO2, CO, O2, H2O, N2O, NH3, NO, SO2, and CH4 in the wavelength region between 1850 and 4000 A. By using a double-beam instrument and a 10-cm path length, we achieved sensitivities of 10−4 cm−1 most of the time, permitting a considerable extension of the literature data.
