Chair of chemical physics 2007 - 2012

چکیده
Chemical physics is a subdiscipline of chemistry and physics that investigates physicochemical phenomena using techniques from atomic and molecular physics. The term was first used by professor A. Eucken in 1930. The main branches of chemical physics are studies of electronic and molecular structure, spectral properties of chemical substances and dynamic behavior of chemical processes. The chair of chemical physics was created in University of Tartu at 1993 and first holder of that position was academician Endel Lippmaa. Peeter Burk has been holding this position since year 2003. Main activities of the chair of chemical physics have been connected with computational modeling of chemical processes and NMR spectroscopy of organic molecules (by Vahur Mäemets). Computational work was first directed towards studies of gas-phase ion-molecule reactions, later several new directions have emerged – studies of zeolites and metal-organic frameworks (Kaido Sillar), quantitative structure activity/properties relationships for predicting physical, chemical and biological properties of molecules (Kaido Tämm), studies of the reaction mechanisms of organic and organometallic reactions (Jaana Tammiku-Taul). The research of the chair of chemical physics have had a clear practical value.

Quasi-particle energies and optical excitations of hydrogenated and fluorinated germanene.
Using density functional theory, the G0W0 method and Bethe-Salpeter equation calculations, we systematically explore the structural, electronic and optical properties of hydrogenated and fluorinated germanene. The hydrogenated/fluorinated germanene tends to form chair and zigzag-line configurations and its electronic and optical properties show close geometry dependence. The chair hydrogenated/...
متن کاملSynthesis, optical and structural characterization of CdS nanoparticles
Cadmium sulfide nanoparticles were grown using wet chemical method by dissolving the reactants of cadmium acetate and sodium sulfide in the presence of thioglycerol (TG) as capping agent in ethanol solvent. Different nanoparticle sizes and size distribution were obtained through varying the molarities of thioglycerol. At higher TG concentration, synthesis provides a nearly monodisperse nanopart...

When the title sulfones, which have non-chair conformations, were stirred with silica gel, elimination of sulfinic acid occurred to give a 1-enitol derivative, if the hydroxyl group at C-6 was protected, whereas such an elimination did not proceed if the hydroxy group was free.
متن کاملThe Conformations of Oxacyclooctanes
The geometries and energies of the conformers of oxocane, the isomeric diand trioxocanes, and of 1,3,5,7-tetroxocane were calculated by molecular mechanics. A boat-chair conformation was preferred by all molecules. From the preference of oxygen in the boat-chair conformations of oxocane (position 3 over 1 over 4) the preferred boat-chair form of all other oxocanes can be derived. The results ar...
متن کاملPolymorphic transformation of dense ZnO nanoparticles: implications for chair/boat-type Peierls distortions of AB semiconductor.
Peierls distortion path was proved experimentally for dense ZnO nanoparticles prepared by static compression. Electron irradiation caused rock salt (R) to wurtzite (W) transition, following preferential (111)(R)//(0111)(W); [011](R)//[1213](W) and then transformation strain induced (111)(R)//(1011)(W); [011](R)//[0111](W). The two relationships can be rationalized by specified extent of chair- ...
