Starr, M. Loewenstein Title: Total absorption cross sections of several gases of aeronomic interest at 584 Å Journal/Source: J. Geophys. Res., 77, 4790-4796, (1972); doi:10.1029/JA077i025p04790 Data: Energy/Wavelength range: 58.4 nm Resolution: Temperature: 295 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: Total photoabsorption cross sections have been measured at 584.3 A for N2, O2, Ar, CO2, CO, NO, N2O, NH3, CH4, H2, and H2S. The absorption cross section of CH4 at 58.43 nm was determined to be sigma = 3.10e-17 (cm2/molecule). Author to whom correspondence should be addressed: (e-mail address):
