Abstract

By the example of phase transition (alpha - beta) in p-dichlorobenzene it is shown, that for phase transition presence of vacancies is necessary. In an ideal crystal, such transition is improbable, that is confirmed with calculations and their consent with experimental information on spectrums of the lattice oscillations.
