Intermolecular potential energy functions and Gruneisen Parameters of simple molecular crystals

A general discussion of the Gruneisen parameter is given and the use to which it may be put in developing a theory of molecular crystals. Calculations are made to effect a comparison between theory and experiment for the lattice Raman bands of crystalline nitrogen (α-form) and their variation with p...

Description
Summary:A general discussion of the Gruneisen parameter is given and the use to which it may be put in developing a theory of molecular crystals. Calculations are made to effect a comparison between theory and experiment for the lattice Raman bands of crystalline nitrogen (α-form) and their variation with pressure. Difficulties in the theoretical treatment of nitrogen are discussed and predictions are made for the case of carbon dioxide, where these difficulties do not apply.
