Abstract

Measurements of O₂ and H₂O absorption line parameters (cross section, linewidth, and line strength) in the 0.7-μm region are presented. In this paper, results for the O₂A band near 760 nm are discussed. We pay particular attention to the ^pP₂₇ line that is useful for temperature monitoring in the atmosphere. The measured absorption cross section and linewidth at NTP are 1.945 10⁻²⁴ cm² · mol⁻¹ and 0.034 cm⁻¹, respectively. We found the linewidth to be 20% lower than the generally adopted value.
