The group of Vladimir Malkin mostly concentrates its work on
development of new quantum chemical methods for calculation of electronic
structure and properties of molecules. Traditionally the central topic was the
calculation of parameters of NMR and EPR spectroscopy by using density
functional theory (DFT) method. Due to the fact that relativistic effects
(first of all, spin-orbit coupling) affects these spectroscopic parameters much
earlier than many other properties of molecules, it was natural that last years
the group pays much attention to relativistic methods to calculate electronic
structure. Lately the major interest starts to shift towards more fundamental
topics: improvement efficiency of the existing QC methods, development of a new
quantum chemical method based on density matrix theory, solving a
time-dependent Dirac-Coulomb equation, going beyond Born-Oppenheimer
approximation. Special attention is paid to development approaches for
interpretation and visualization of the calculated properties of molecules.
While we traditionally still use the old deMon code, all new
developments are implemented in the ReSpect (Relativistic Spectroscopy)
program.
