The Crystalline State, solids and liquids the distance between neighboring atoms is of the order of a few Angstroms, i.e., they contain 10.–10. atoms per cm.. This may be compared with a density of about 2.7 × 10. molecules per cm. in a gas at room temperature under one atmosphere, corresponding to an average distance of

Now, . is, except for an arbitrary constant, determined uniquely by the temperature and volume of the system. Hence. and (2-1) may be rewritten in the form .The specific heat in

Since the interstitial positions provide room only for relatively small atoms, interstitial solid solutions are likely to be formed with the elements H, B, C, N, and O; the approximate radii of the

Dielectric and Optical Properties of Insulators,ven here is essentially classical ; for the quantum theory of dielectrics we refer to the literature (see, for example, J. H. van Vleck, ., Oxford, New York, 1932). This chapter is divided into two parts : in part A we shall essentially be concerned with the static dielectric constant, in part B the
