KHUSHVAKTOV KHAKIM ABDULKHAKOVICH

Doctor of Physical and Mathematical Sciences, Associate Professor, Vice-Rector of Samarkand State University

 

Research Direction:

 

Study of the mechanisms of molecular cluster formation and their properties using vibrational spectra. Determination and analysis of spectroscopic parameters of nanosized molecular clusters in biological objects and development of recommendations for practical use of these objects.

The main results of scientific research:

In substances consisting of highly polar molecules in liquid and crystalline states, the mechanisms of formation of clusters up to 10 molecules in number have been established, a complex system of molecular cluster formation processes has been established; the role of intramolecular and intermolecular hydrogen bonds in the formation of cluster structures of highly polar substances in liquid and isolated states, as well as geometric and electro-optical parameters of clusters have been established; a new spectroscopic interpretation of the bands associated with the O-H vibrations has been presented; a new spectroscopic interpretation of the bands associated with the O-H vibrations has been presented; the role of intramolecular and intermolecular hydrogen bonds in the formation of cluster structures of highly polar substances in liquid and isolated states, as well as geometric and electro-optical parameters of clusters.
