Research profile

Physical and theoretical chemistry: chemical applications of the Density Functional Theory. Electronegativity and chemical hardness of bonded atoms and chemical groups as the guiding parameters for the chemical reactivity. Analysis of the effect of coupling between molecular vibrations and deformations of the electronic structure. Important phenomena where this effect is evident are: (i) vibrational frequencies in molecules adsorbed on solid surfaces; (ii) proton motion within the hydrogen bond; (iii) activation energy on the reaction trajectory.
