Recent research achievements

 

Explanation of the nature of chemical bonding in molecular systems containing rare gas atoms.

Proposition of new method for calculations of the basis set superposition error for many-body clusters.

The protein folding and protein structures belong to the most important issues of chemistry today.

The nature of the H-bonding interactions play a fundamental role in the energetics of peptide structures.
We need to understand the effects of structural modifications upon the energetics of proteins including those
influencing primary, secondary, and tertiary structural properties. The influence of environmental factors, such
as solvation, certainly plays an important role in protein-folding modeling, we also emphasize the necessity
of understanding the intrinsic energetics of peptides (i.e., in the absence of solvation) in order to better differentiate
the importance of the intrinsic and environmental influences. We examine the effects of H-bond cooperativity, relative
energies of alpha-helices to beta-strands, the influence of side chains on backbine, IR modes coupling, the distortion effects upon protonation, the peptide-solvent interaction. The results of quantum-chemical research on that field we have recently published in seven papers in JACS.
