"Physics of Cryocrystals offers the first comprehensive treatment of molecular cryosolids. The book focuses on the distinctions between molecular and atomic cryocrystals, especially on the role of molecular rotation. Also considered are how cryocrystals are used for investigating the lattice dynamics of crystals with isotropic and anisotropic interactions, phase transitions, melting, different kinds of electronic excitations in insulators, and impurity effects. Detailed tables and graphs of molecular parameters, essential thermodynamic data, and lattice-dynamic data serve to make Physics of Cryocrystals an invaluable sourcebook."
