It is shown, that values of frequencies of lines in a spectrum of the lattice oscillations of the molecular films are depressed in comparison with values of frequencies of similar lines in a monocrystal. Intensity of padding lines will increase in a spectrum of films. Allocation of an impurity in a film of an organic mixed crystal nonuniform. Examinations are lead by the example of a p-dibromobenzene and the mixed crystal a p-dichlorobenzene / p-dibromobenzene.3 pages, 1 table, 1 figureOpticsAtomic and Molecular Clusterstext
