Seven review articles and original papers provide a representative overview of the research work done in hydrogen bond research at Austrian universities. The topics covered by the contributions are: state-of-the-art of understanding hydrogen bonding in biopolymers; recent NMR techniques for studying hydrogen bonding in aqueous solutions; intramolecular hydrogen bonding and proton transfer in a class of Mannich bases derived from substituted phenols and naphthols; competition between intramolecular hydrogen bonds in ortho-disubstituted phenols; molecular dynamic simulations on proton transfer in 5,8-dihydroxynaphthoquinone and in the formic acid dimer; accurate calculations of the intermolecular interactions in cyanoacetylen dimers; correlation between OH...O bond distances and OH stretching frequencies as derived from structural and spectroscopic data of minerals.
