The main direction of our work is development of electronic structure calculation methods for molecules containing heavy elements. The aim is to elaborate technique and programs which allow one to perform very accurate calculations providing smallest computational expenses. It can be reached with the help of "two-step" methods which enable to "split" the correlation structure calculation of such molecules on two consequent calculations in valence and core regions.
This activity was initiated by the experimental study of the Parity Non-Conservation (PNC) effects in such molecules as TlF and YbF and started in 1982 with PhD work of A.Titov. Thesis " Effective Potentials and Generalized Brillouin Theorem for electronic states of molecules" was defended in 1986. In 1996, PhD thesis "Development of Relativistic Effective Core Potential method" ( .dvi file - in Russian. Brief review of the thesis .dvi file - in Russian.) was defended by N.S. Mosyagin where topics related to generation of the Generalized Relativistic Effective Core Potentials (GRECPs) and RECPs for transition and rare-earth elements were considered.
Now we are working in the following directions:
