Short summary
Previous publications on the absorptions of the oxygen dimer O2–O2 (or short: O4) list absorption peaks at 328 nm and 419 nm, for which no spectrally resolved literature cross sections are available. As these absorptions potentially influence the spectral retrieval of various other trace gases, their shape and magnitude need to be quantified. We approximate the absorption peaks at 328 nm and 419 nm by their respective neighboring absorption peaks to estimate their magnitude and peak wavelength.
