The course is targeted mainly on the student with zero knowledge of computational chemistry, oriented on inorganic, organic and macromolecular chemisty. It concentrates on practical use of Gaussian and PCGamess computational programs. Special attention is devoted to vizualization of the computational results, as optimized geometries, infrared and NMR spectra, electrostatic potential and reaction mechanisms, using both commercial (GaussView) and free of charge available (Molekel, WxMacMolPlt, ArgusLab etc.) programs.
