Pressure broadening measurements of the 118.750 GHz oxygen transition

Abstract
New low‐pressure measurements of the oxygen transition at 118.750 GHz have been made with a magnetically modulated cavity spectrometer at 298 °K. The line broadening parameters for collision with oxygen, nitrogen, water, helium, and argon are 2.131±0.037, 2.20±0.10, 2.30±0.24, 1.605±0.060, and 2.014±0.091 MHz/torr, respectively.
