Pressure dependence of the lattice parameters of naphthalene up to 5.5 kbar and a re-evaluation of the elastic constantssa)

Abstract
The pressure dependence, up to 5.5 kbar, of the lattice parameters of naphthalene was determined, using neutron diffraction techniques. The variations were fitted to straight lines, the slopes of which are the linear compressibilities. The volume compressibility at 5 kbar was found to be in good agreement with the values obtained by Bridgman and by Vaidya and Kennedy. A set of elastic constants for naphthalene was calculated using the experimental values of the linear compressibilities. This set is found to be in close agreement (except for C11) with a set calculated by Pawley, who used the general intermolecular potential of Kitaigorodskii.
