摘要

The interactions between 22 organic and inorganic compounds of different nature with copper (II)-diethilentriamine complexes, covalently bonded to silica, were studied. It was shown that by the grade of influence on the ESR spectrum of complexes the compounds can be divided into three groups. To the 1-st group appertain quinoxaline-2,3-dithiol and SCN~- which change parameters of spin-hamiltonian essentialy and can be detected selectively. To the 2-nd one belongs a list of sulfur containing ligand, for example, Michler thioketone and thiosalicylic acid which lead to disappearance of the spectrum for bonded complexes. To the 3-rd group pertain substances which have no obvious influence on the spectrum's parameters (Br~- OH~-, NO_2~- C_2O~2-).
