PHYSICO-CHEMICAL RESEARCH DEPARTMENT

The Department of Physico-Chemical Research (initially the Department of Molecular Structure and Spectroscopy) was founded in 1968 by Professor Yu.P.Egorov. Since 1994 PhD M.I.Povolotskii is the Head of the Department.
The staff of the Department is as follows: 1 Doctor of Science, 6 PhDs and 9 engineers.
The modern organic and organo-element chemistry is unimaginable without physical-chemical investigation of the molecular, electronic and crystalline structure of new compounds.
The characteristic peculiarity of the Department is the possibility to apply complex methods of X-Ray structural study of mono-crystals, multi-nuclear and dynamic NMR, optical spectroscopy and quantum-chemical calculations for study of spatial and electronic structure of organic and organo-element compounds [1]. The Department includes also an Analytical Laboratory using classical methods of chemical and chromatographic analysis. This complex approach allows to obtain a unique information about the structure and reactivity of new and described compounds.
The priority direction of the Department research work is investigation of the phosphorus compounds with unusual co-ordination. A variety of three-valence one- , two-coordinated phosphorus and ?3, ?5-phosphoranes – derivatives of five-valence three-coordinated phosphorus have been studied with the help of multi-nuclear NMR spectroscopy, X-Ray structural and quantum-chemical methods.  Integrated information allowed to establish the foundations of structural chemistry of organo-phosphorus compounds with non-classic coordination.
The usage of modern theories allowed to explain the nature of the substituents influence in the compounds of low-coordinated phosphorus and unusual chemical shifts in NMR spectra, characteristic for the named classes of compounds [2].
The scientists of the Department fruitfully collaborate with the colleagues in the Institute and other scientific institutions in the Ukraine and abroad.
The Center of joint scientific equipment usage “X-Ray Mono-crystal Diffracometry” has been created in the Institute for the most efficient usage of the unique and expensive X-Ray mono-crystal diffractometry complex APEX II (“Bruker” production).
The Department conducts theoretical calculations of the structure, reactivity and spectral characteristics of chemical compounds in the frames of collaboration with the colleagues from Germany and USA. The modern calculation methods allow to model complex supramolecular systems [3].
