The proton motion in hydrogen bonded quasi-one-dimensional molecular chains is investigated It is shown that elementary processes in one-dimensional ice lattice are nonlinear ailtolocalized collective exittttions which can spread over macroscopic distanced retaining the energy, momentum, and charge. The results obtained can be used to explain some phenomena in biological systems.B O E O P O~H O~ C B R B~I O . n o~a 3 a~0 , w o a n e w e~~a p~~e npo~eccbi B omomepHol pewewe

The lower-energy portions of the potential energy surfaces of superoxide hydrates O2(-)(H2O)(1< or = n < or = 4) are thoroughly investigated at high computational levels. The structural, energetic and spectroscopic features of the stable superoxide hydrates on these potential energy surfaces are discussed, focusing in particular on some implications to their infrared spectra and the hydrogen bond trends. The present work reports the transition-state linkers between the most stable superoxide hydrates which are useful to understand the energetics of their mutual interconversions.
