Реферат: The EPR method was used to study the spatial organization of linear polytrimethyleneimine (P) globules containing various amounts of coordination-bonded Cu(II) ions in vitrified 50% aqucous-methanolic solutions at 77 K. Calculations of the EPR spectra gave refined spin-Hamiltonian parameters and revealed the presence of triaxial anisotropy, that is, tetrahedral distortions of copper coordination centers in P. Cu(II), Ni(II), and Zn(II) ions were shown to equiprobably fill P globules at low [Cu(II)] concentrations. At copper concentrations higher than 0.01 mol/l, the distribution of complexes in a globule becomes nonuniform. At all [Cu(II)] values, the local concentrations of 〈Cu〉 complexes in P are substantially lower than in polyethylencimine globules.
