FEATURES OF STRUCTURAL-PHASE TRANSFORMATIONS IN THIN FILMS OF CRYOVACUUM CONDENSATES OF ETHANOL
Abstract
The article presents the results of an experimental study of thermally stimulated polyamorphic and polymorphic transformations in cryovacuum condensed ethanol films formed at a substrate temperature T = 16 K. The studies were carried out on a modified cryovacuum spectrophotometer in the frequency range of the IR spectrometer from 4200 to 400 cm-1. New data have been obtained on the temperature ranges of existence of ASE (amorphous solid ethanol), structural glass (SG- structural glass), during ultrafast cooling of a liquid (SCL- supercooled liquid), plastic crystal (PC- plastic crystal), orientationally disordered crystal (ODC- orientationally disordered crystal), fully ordered monoclinic crystal (MC- monoclinic crystal). The data obtained are consistent with modern concepts of transformations in cryovacuum condensates of ethanol.
