Sažetak

Different dynamical properties of the hydrogen bond and
charge transfer complexes are described from the same point of
view. An introduction of a coupling parameter responsible for the
A-Z and A· · · B mode interaction in the system A-Z · · · B (Z is
the hydrogen or halogen atom) permits to interpret quantitatively
some empirical findings and regularities. They are the A-Z bond
length increasing on complexing, the A-Z stretching band shift
towards lower frequencies and its linear dependence on the A-Z
bond lengthening, the isotopic effects for the A· · · B and A-H bond
lengths and for the A-H stretching frequency, the A-Z vibrational
band broadening on complexing in the liquid phase and a
dependence between the band halfwidth and the frequency shift.
Some relations containing no fitting parameters are established
in a good agreement with experiment.
