science-softCon uv/vis+ photochemistry database; www.photochemistry.org; (C) science-softCon 2019 Substance: oxygen Other names: Formula: O2 CAS-No.: 7782-44-7 Study: absorption cross section Authors: B.R. Lewis, S.T. Gibson, M. Emami, J.H. Carver Title: Resonances in the photodissociation of isotopic molecular oxygen-I. The longest band Journal/Source: J. Quant. Spectr. Rad. Transfer, 40 (1), 1-13, (1988); doi:10.1016/0022-4073(88)90025-8 Data: Energy/Wavelength range: ~ 115 - 180 nm Resolution: 0.04 - 0.06 Å FWHM Temperature: 79 K; 295 K Temperature dependence: yes Pressure/Concentration: Phase: pH: Comments: The isotopes 16O2, 16O18O and 18O2 were studied at 79 and 295 K, with an instrumental resolution of 0.04-0.06 Å FWHM. The maximum absorption cross section of O2 at lambda = 124.4 nm was measured to be 92 Mb at 79 K. Author to whom correspondence should be addressed: (e-mail address):
