Bibliothèque de L'IMIST/CNRST

Includes bibliographical references and index.

Dynamics of the molecular crystal lattice -- Calculation of frequencies and normal vibrational forms in the approximation of rigid molecules -- Solution of the dynamical problem with the consideration of the intermolecular vibration -- Devices and methods for the experimental investigation of organic crystals by means of the vibrational spectra -- Vibrational spectra and phase transitions in plastic crystals -- Reorientational motion of molecules in crystals without mesophases -- Stationary orientational disorder in trihalogen substituted methane crystals -- Vibrational spectra and phase transition in crystals with conformationally unstable molecules -- Application of vibrational spectra and AAP for the determination of structures and the investigation of phase transitions in crystals of phenanthrene and pyrene.

The current volume is a single topic volume on the optical spectra and lattice dynamics of molecular crystals. The book is divided into two parts. Part I covers both the theoretical and experimental investigations of organic crystals. Part II deals with the investigation of the structure, phase transitions and reorientational motion of molecules in organic crystals. In addition appendices are given which provide the parameters for the calculation of the lattice dynamics of molecular crystals, procedures for the calculation of frequency eigenvectors of utilizing computers, and the frequencies and eigenvectors of lattice modes for several organic crystals. Quite a large amount of Russian literature is cited, some of which has previously not been available to scientists in the West.
