Acoustic velocity data for various isotherms from 1 to 70 atm. are presented for argon (32°F.), nitrogen (32°F.), methane (32°, 70°F.) tetrafluoromethane (32°, 70° F), dichlorodifluoromethane (240°F., p < 30 atm.), and various mixtures (32°F.). Interaction potential force constants for the pure gases are derived from the acoustic data with values for tetrafluoromethane and dichlorodifluoromethane differing significantly from previous literature values. BWR constants are also reported for argon and tetrafluoromethane.
