Collisions induced absorption spectra of pure oxygen and gaseous mixtures
of oxygen and nitrogen were measured at laboratory and studied, in the region
of 1.06 μm, using Cary 5000 spectrophotometer, and White absorption gas cell
with a path length
fixed at 9.6 m. The mixing ratio of oxygen in nitrogen were
20%, 50% and 80%, at temperature 298, 323, 348, 373 K and pressures
between 1 and 25 bar. The absorption band was centered at 1.06 μm, and
raised as a wide continuum absorption, and did not show any rotational
structure.
