Abstract (English):
The vibrational spectra of 1,2-dichloroethane solutions in a glass matrix (wax oil) at a wide temperatures interval including below glass-transition temperature has been investigated. It is revealed that at concentrations more than 0,07 i.v.f. the complexing signs are observed. The joint analysis of experimental data with factor analysis and quantum-chemical calculation methods has allowed to establish that the molecular complex is the dimer formed by trans- and gauche-conformations of 1,2-dichloroethane. The thermodynamic parameters of the complex were determined.
