“…In the region from 2450 to 2800 A, a series of diffuse bands, each consisting of three peaks, is shown. These bands were first reported by Finkelnburg and Steiner, 14 and their wavelengths, as indicated in Fig. 4 on the peaks of the bands, agree with present observations.…”

The total absorption of radiation in the 2000-2800 A region has been measured for 0 2 . The absorption does not follow Beer's law. The linear increase in the measured effective absorption cross section with rise in gas pressure is ascribed to the absorption caused by 0 4 . With methods developed and presented recently by the writer, the absorption cross sections of 0 2 and 0 4 are derived from total absorption measurements.

“…The latter are obtained from our recent rotational analysis of the AЈ 3 ⌬ u state (24). The intervals between the peaks are consistent with previous studies (9,10). They are close to the values of the triplet splittings for the AЈ 3 ⌬ u state, which vary from 149.6 to 118.2 cm Ϫ1 for vЈ ϭ 2 to 11, according to the spin-orbit coupling constants A derived by Jenouvrier et al (24).…”

Absorption spectra of molecular oxygen were measured in the laboratory under temperature and pressure conditions prevailing in the Earth's atmosphere. Spectra of pure O 2 , O 2 ϩ N 2 , and O 2 ϩ Ar were recorded in the 41 700 to 33 000 cm Ϫ1 region (240 -300 nm) at a maximal optical path difference of 0.45 cm using a Fourier transform spectrometer and a multiple reflection gas cell. The different components of the spectra, namely the discrete bands of the three Herzberg systems, the Herzberg continuum, and the collision-induced diffuse Wulf bands, were separated. The contribution of the Herzberg bands was first subtracted using the line parameters determined previously [A. Jenouvrier, M.-F. Mérienne, B. Coquart, M. Carleer, S. Fally, A. C. Vandaele, C. Hermans, and R. Colin, J. Mol. Spectrosc. 198, 136 -162 (1999)] from high-resolution data. Spectra recorded at various pressures then made it possible to determine by linear regression the intensity of the Wulf bands and the Herzberg continuum. The characteristics of the Wulf bands have been investigated in details: vibrational analysis, pressure effect, foreign gas effect, and a simulated spectrum are reported. The Herzberg continuum cross section is determined below the dissociation limit. A comparison with literature data is given. The new O 2 absorption cross sections and O 2 -O 2 collision-induced absorption cross sections are useful in connection with atmospheric measurements of ozone and other trace gases in the UV spectral region.

“…by Wulf [17], and have since been reported by several authors [18,19]. The nature of the Wulf bands whose intensity is proportional to the square of the pressure is still controversial: They are attributed either to the 04 dimer, to the (02) 2 collision complex or to collision-induced absorption (CIA) [19][20][21][22].…”

Absorption spectroscopy, which is widely used for concentration measurements of tropospheric and stratospheric compounds, requires precise values of the absorption cross-sections of the measured species. NO v 02 and its collision-induced absorption spectrum, and H20 absorption cross-sections have been measured at temperature and pressure conditions prevailing in the Earth's atmosphere. Corrections to the generally accepted analysis procedures used to resolve the convolution problem are also proposed.
