Shapes of oxygen absorption lines in the microwave frequency region

Abstract

This report concerns measurements of oxygen microwave absorption line widths and intensities of the significant lines between 58 and 62 kilomegacycles per second. These measurements were made at pressures ranging from 0.25 to 20.6 mm of Hg. The values obtained for the line widths of these eight lines ranged from 1.39 to 1.85 Mc/s/mm of Hg. Their measured intensities were from 4.73 to 8.85 db/km. Values for N2/O2 broadening ratios were determined for this pressure range for the two lines at 61.1 and 61.8 kMc/s. Correlation with the results of other investigators is shown.
