Freeman Title: Absorption Cross Section Measurements of Oxygen in the Wavelength Region 195-241 nm of the Herzberg Continuum Journal/Source: Planet. Space Sci., 34, 1007-1021, (1986); http://dx.doi.org/10.1016/0032-0633(86)90011-5 Data: diagram, table Energy/Wavelength range: 195 - 241 nm Resolution: 0.13 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: 5 - 760 Torr Phase: gas pH: Comments: The continuum cross section of oxygen at 296–300 K has been measured with a resolution of 0.13 nm throughout the wavelength region 205-241 nm with oxygen pressures from 5 to 760 torr and optical path lengths from 13.3 and 133m. The values of the Herzberg continuum cross section of oxygen, tabulated at 1 nm intervals in the region 195-241 nm, increase from 6.3 × 10-24 cm2 at 195 nm to a maximum of 6.6 × 10-24 cm2 at 201 nm and then decrease to 0.85 × 1024 cm2 at 241 nm.
