SPECTRAL INVESTIGATION OF TRIPHENYLFORMAZAN DERIVATIVES IN ULTRAVIOLET LIGHT

摘要

Four triphenylformazan derivatives were studied in various solvents aiming to reveal the types of intermolecular interactions. Solvent influence on UV absorption band was analyzed using graphs of spectral shift versus functions of solvent macroscopic parameters. The dominancy of dispersive interactions was evidenced, as well as some specific interactions. The HyperChem algorithms allowed getting additional data regarding microscopic parameters of triphenylformazans.
