Paper Abstract

The method of IR spectroscopy for a quantitative evaluation of a structure anisotropy of metastable organic polycrystalline films is offered. In the method the division of an inverse problem of complex optical parameters determination into a number of stages with optimization on no more than two unknown parameters is used. It provides a capability of graphic support of optimization process and, as a result, minimization an error and operating correction of a possible ambiguity at each stage of the inverse problem solution. It is shown that for polycrystalline films the degree of crystallites orientation f is determined by ratio of their anisotropy. Its relation to the common used degree of crystallites orientation, which can be introduced properly only in a case of weakly absorbing films, is considered. The described method is used for investigation of optical and structural parameters of anisotropic polycrystalline copper phthalocyanine films of α-form in bands of a weak absorption (nonplanar molecular oscillations and plane skeleton deformation oscillations at about 769 cm-1 and 754 cm-1, respectively).
