Investigation of Organic Nanocrystallic Films by the Method of Raman Spectroscopy

Abstract

Investigation of organic molecular films by a method Raman of a spectroscopy is carried out. 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.
