Abstract
Measurements have been made of the heat capacity Cp from ∼14 to 300°k of three clathrates of krypton and β-quinol, in which 24·2, 47·9 and 79·5 per cent of the cavities were occupied by krypton. Cp was found to be a linear function of composition. These results together with those previously obtained for the argon clathrate make it possible to fix within comparatively narrow limits a distance parameter characteristic of the quinol lattice (in effect a measure of the thickness of the wall of the cavity). This should make it possible to carry out a reliable analysis of the contribution made to the heat capacity of quinol clathrates by diatomic and polyatomic molecules.
