The optical Kerr effect (OKE), a well known non-demolition optical method for the investigation of matter, yields useful information concerning molecular interactions and local fields in a medium. However, the interpretation of the results obtained in dense media is beset with many difficulties, especially when it comes to determine the contributions of different types of molecular interactions to the optically induced birefringence. Due to the enhancement in sensitivity of our experimental device,1 OKE measurements in gases and vapours, where the molecular interactions can be pressure-controlled, have now become feasible. Here, we report OKE measurements in liquid and gaseous carbon dioxide and the temperature-dependence of this effect, from which some information concerning the molecular interactions and local molecular fields of the medium can be obtained.
