✦ Synopsis

In their 1949 investigation of the infrared spectrum of high-pressure carbon dioxide gas, Welsh et al.

[1] observed two intense collision-induced absorption (CIA) bands near 1285 and 1388 cm Γ€1 , with integrated intensities proportional to the square of the pressure. The two bands overlap the expected positions of the Fermiresonant infrared-inactive R ΓΎ g -symmetry m 1 and 2m 0

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 Ο© N 2 , and O 2 Ο© Ar were recorded in the 41 700 to 33 000 cm Οͺ1 region (240 -300 nm) at a maximal optical path difference
