Biography
Dr. Jan Najbar is the Professor of Chemistry in Jagiellonian University. Research carried out by their group is in the field of physical chemistry related to photophysics and photochemistry of organic molecules, and to laser spectroscopy. In particular, they perform studies of intramolecular and intermolecular interactions infl uencing the rates of radiative and radiationless processes. The emphasis is on the early events that follow light absorption and the spin-orbit interactions in molecules and in weak complexes. Our research topics include: (i) the ultrafast electron transfer processes and salvation dynamics, (ii) spectroscopy of jet-cooled organic molecules, (iii) laser induced fl uorescence, (iv) deuteration effects, (v) theory of ultrafast photochemical reactions in solutions, (vi) charge separation phenomena in triad systems, (vi) effects of the electric field on electron transfer reactions, (vii) roles of the spin dynamics in multistep electron transfer processes.
