Praca dotyczy badań teoretycznych zjawiska tunelowania protonu w wiązaniu wodorowym na przykładzie układu imidazol - kation imidazolowy. Dla przedmiotowego układu przeprowadzono obliczenia dotyczące struktury elektronowej metodą ab initio CASSCF. Uzyskano zoptymalizowaną strukturę równowagową kompleksu, strukturę stanu przejściowego (transition state) oraz ich energie elektronowe. Obliczono też częstości drgań układu w geometrii równowagowej. Wykorzystując obliczone całkowite energie elektronowe dla badanego układu w geometrii równowagowej oraz dla geometrii stanu przejściowego dopasowano modelowy potencjał dwuwymiarowy opisujący sprzężenie drgania rozciągającego N-H (tunelującego) o wysokiej częstości z niskoczęstościowym drganiem rozciąga...
