The Dielectric Constant of Several Gases at a Wave-Length of 3.2 Centimeters

The dielectric constants of dry air, oxygen, water vapor, ethyl alcohol, ethyl chloride, chloroform, and acetone have been measured at a frequency of 9340 megacycles using the beat frequency method. With the exception of water vapor, the measurements were made at room temperature. For water vapor measurements were made over a temperature range of 293 to 342 degrees Kelvin.
