Recent aspects of the proton transfer reaction in H-bonded complexes

Anomalous electrical conductivity of aqueous solutions in submicron cracks and gaps

“…These observations suggest there must be some particular property of aqueous solutions, which is most pronounced at the metal-solution boundary and quickly weakens with the distance from the boundary. Such a property could be a spatial hydrogen-bonded network (HBN) possessing an ice-like structure close to the metal surface [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. This supposition is based on the following data: 1. a high electrical conductivity is obtained for ice at a sufficiently high concentration of charge carriers [17][18][19][20].…”

“…This supposition is based on the following data: 1. a high electrical conductivity is obtained for ice at a sufficiently high concentration of charge carriers [17][18][19][20]. A similar situation could exist in liquid provided that there is a sufficiently widely branched and relatively ordered bonded network of similar molecules involving hydroxyl groups and characterized by short-range interactions; 2. high conductivities of solvents with a HBN [21][22][23][24][25][26] to which water, but not alcohols, belong. Such a bonded network is labile, stable against external effects, and able to transmit perturbations over the whole volume [21][22][23]; and 3. a similar network can exist in the ordered layered structure of water adsorbed on nonmetals, silver, gold, and platinum [14,[30][31][32].…”

Spectroscopic studies of the 1:1 complex of piperidine-4-carboxylic acid (isonipecotic acid) with 2,6-dichloro-4-nitrophenol

“…When the proton is located at a point of a crystal symmetry, the IR spectrum of the molecules linked through a strong hydrogen bond shows a broad absorption in the region between 1500 and 600 cm -1 . [32][33][34][35][36]. This bond indicates an easily polarizable system characterized the presence of narrow negative bands, called "windows" or "Evans holes" [37].…”

Multiphoton ionization and ab initio calculation of the hydrogen‐bonded clusters (C5H5N)n(NH3)m

“…The hydrogen bond plays an important role in the formation and reaction of many molecular clusters, including many biological supermolecules. Studies on hydrogen bond clusters have been a ‘hot topic’ recently 1…”
