Lattice Dynamics and Thermal Crystallographic Parameters in Phenothiazine
(International Union of Crystallography, 1984)
A computer program has been developed to study the lattice dynamics of molecular crystals in the harmonic approximation with the external Born-yon KS.rm~n formalism and an atom-atom potential function. Dispersion curves ...
