About Me

I joined Ball State University in 2016 after doing research and teaching at National Academy of Sciences of Ukraine, University of Houston, and Roosevelt University (Chicago). I study unusual interactions (anion-π and halogen bonding, -bonding of radicals). These counter-intuitive bondings determine how molecules recognize each other and how they react in chemical and biochemical systems, and what are properties of materials they form.

My College Experience

I received my M.S. in Chemical Physics from Moscow Institute of Physics and Technology and Ph. D. in Chemistry from Institute of Physical Chemistry of the National Academy of Sciences of Ukraine in Kyiv. I started my research of thermal and photochemical reactions of macrocylic compounds as an undergraduate student, and this was vital for my development as a scientist

What I have Learned?

I was doing research in academy and collaborated with industry for many years and have seen that chemistry is a central undivided science. A good knowledge of the basics of physics, mathematics and physical chemistry is very helpful for solving variety of problems in inorganic, organic and analytical chemistry, as well as for practical industrial applications

Degree History

Institute of Physical Chemistry of National Academy of Sciences of Ukraine Ph.D. (1988)
Moscow Institute of Physics and Technology M.S. (1984)

Rosokha Research

Our research is focused on the intermolecular interactions and their role in chemical reactions. Primarily, we study halogen bonding’ an attraction between halogen atoms and electron-rich centers, and anion-π bonding, a counter-intuitive attraction between anions and aromatic or olefinic systems. Such interactions were recently identified in many chemical and biochemical systems and several publications demonstrated their significant potential for variety of applications, from crystal engineering of conducting and magnetic materials and molecular recognition, to control of chemical reactivity and rational design of pharmaceutical compounds. This project is supported by the grant CHE-1607746 “RUI: Supramolecular anion-pi and halogen-bonded complexes and their role in electron-transfer processes” from the National Science Foundations (Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry).

We also study intermolecular pi-bonding involving ion-radicals. Elucidation of such interactions provides fascinating data for the development of fundamental concept of chemical bonding. Also, this bonding is vital for the reactions of the ion-radical in solutions and conductivity of their salts, which frequently show unusual magnetic and (super-) conducting properties. This project is supported by the grant PRF #56516 “Characterization of ion-radicals’ pi-bonding and electron transfer using cation-radical salts with weakly-coordinating anions” from the American Chemical Society Petroleum Research Fund.

Students participating in research projects: (i) gain skills in basic organic and inorganic synthesis, common spectral (UV-Vis-NIR, FT-IR) and electrochemical measurements, crystallization of solid-state materials; (ii) enhance knowledge of chemical bonding, thermodynamics, kinetics and reaction mechanism, (iii) get experience in scientific literature analysis, data evaluation, preparation of reports and manuscripts.
