Laboratory for Quantum Mechanics and Molecular Radiation Processes

Modeling physical and chemical properties, highly excited quantum states of molecules and radiation processes for application in nonlinear dynamics, spectroscopy, remote analysis, atmospheric optics, astrophysics, chemistry, biophysics, and ecology.

**Research outcomes:**

The research group published calculations of potential energy surfaces of small and polyatomic molecules. The group developed algorithms for calculating the spectra of the calculated energy surface and dipole moment. A computer implementation of the method of contact transformations for polyatomic molecules of different types has also been developed. On the basis of the proposed model the group conducted theoretical research on the photophysical properties of a wide number of organic molecules for applications in photonics and organic electronics. The laboratory conducted research on magnetic properties of heteroporphyrin and isoflurane molecules, and theoretical research on the photophysical properties of porphyrin and some of its derivatives and complexes with lutetium, and new zinc metalorganic complexes.
