Vibrational spectra and the formation of partially disordered systems with microheterogeneous nanocrystalline structure

摘要

This article is devoted to the intermolecular vibrational spectra and structural features of solid systems that possess microheterogeneity due to finely dispersed shattering of the Substance, with the formation of nanocrystals. It is shown that the methods of obtaining nanocrystallites (crystallization from the melt, adsorption in pores, impact-acoustic action) play a substantial role. Common regularities in the observed variation of the intermolecular vibrational spectra are detected in a large number of molecular and ionic compounds as one goes from an ordered, homogeneous structure to microheterogeneity.
