Double Molecules in Gases

Abstract

WE have observed double molecules, for example (CO2)2, in carbon dioxide, nitrous oxide, nitrogen, oxygen, argon and xenon. It is believed that these double molecules exist in all gases at temperatures where the attractive Van der Waals interaction is of importance, and where the pressure is sufficiently high to produce a significant fraction of three-body collisions. Their existence has been predicted for many years1.
