Abstract
An extremely strong H/D isotope effect observed in hydrogen bonded A-H…B systems is connected with a reach diversity of the potential shape for the proton/deuteron motion. It is connected with the anharmonicity of the proton/deuteron vibrations and of the tunneling effect, particularly in cases of short bridges with low barrier for protonic and deuteronic jumping. Six extreme shapes of the proton motion are presented starting from the state without possibility of the proton transfer up to the state with a full ionization. The manifestations of the H/D isotope effect are best reflected in the infra-red absorption spectra. A most characteristic is the run of the relationship between the isotopic ratio νH/νD and position of the absorption band shown by using the example of NHN hydrogen bonds. One can distinguish a critical range of correlation when the isotopic ratio reaches the value of ca. 1 and then increases up to unusual values higher than . The critical range of the isotope effect is also visible in NQR and NMR spectra. In the critical region one observes a stepwise change of the NQR frequency reaching 1.1 MHz. In the case of NMR, the maximal isotope effect is reflected on the curve presenting the dependence of Δδ (1H,2H) on δ (1H). This effect corresponds to the range of maximum on the correlation curve between δH and ΔpKa that is observed in various systems. There is a lack in the literature of quantitative information about the influence of isotopic substitution on the dielectric properties of hydrogen bond except the isotope effect on the ferroelectric phase transition in some hydrogen bonded crystals.

Abstract
The intermolecular geometric isotope effect (GIE) in hydrogen bond A-X···B (X = H and D) is investigated theoretically using the nuclear orbital plus molecular orbital (NOMO) theory. To interpret the GIE in terms of physically meaningful energy components such as electrostatic and exchange-repulsion interactions, the reduced variational space self-consistent-field method is extended to the NOMO scheme. The intermolecular GIE is analyzed as a two-stage process: the intramolecular bond shrinkage and the intermolecular bond elongation. According to the isotopic shifts of energy components described by the NOMO/MP2 method, the intermolecular GIE is approximately interpreted as a process reducing the exchange-repulsion interaction after the decrease of electrostatic interaction.

Abstract
We consider the coupled dipole-proton system of hydrogen-bonded ferroelectric crystal with one defect dipole that is coupled more strongly with the protons than the original dipole. This defect dipole simulates the symmetry-breaking defects that are often introduced in the crystals as probes in the electron paramagnetic resonance (EPR) experiments. A particular attention is paid to the explanation of strong isotope effects that have been detected in the measurements of static and dynamic properties of the pure crystals and the symmetry-breaking defects. We suppose that the isotope effects are caused by the isotope-dependent tunneling energy and we analyze behavior of the system with and without the defect in two adiabatic approximations that correspond to the case when the protons tunnel faster than the dipoles oscillate and to the opposite case. These two approximations lead to the two models which predict different properties the pure crystals and the symmetry-breaking defects.

Abstract
We measure the effects of low concentrations of helix-stabilizing cosolvents, including 2,2,2-trifluoroethanol (TFE), on the thermodynamics and kinetics of folding of the dimeric alpha-helical coiled coil derived from the leucine zipper region of bZIP transcriptional activator GCN4. The change in kinetic behavior upon addition of 5% (v/v) TFE indicates that it stabilizes the transition state to the same degree as the fully helical native state. However, folding rates are largely insensitive to alanine to glycine mutagenesis, indicating that the majority of helical structure is formed after the transition state. Equilibrium hydrogen isotope partitioning measurements indicate that intramolecular hydrogen bonds are not strengthened by TFE and that amide hydrogen bonds in the transition state are nearly the same strength as those in the unfolded state. Thus, the mechanism by which TFE exerts its helix-stabilizing effects can be divorced from helix formation and does not depend on the strengthening of intrahelical hydrogen bonds. Rather, TFE increases the structure of the binary alcohol/water solvent, thereby increasing the energetic cost associated with solvation of the polypeptide backbone. At low concentrations, TFE destabilizes the unfolded species and thereby indirectly enhances the kinetics and thermodynamics of folding of the coiled coil. A high degree of polypeptide backbone desolvation, and not the formation of regular helical structure and native strength hydrogen bonds, is the critical feature of the transition state for folding of this small dimeric protein.

Abstract
Hydrogen bonds are a key feature of chemical structure and reactivity. Recently there has been much interest in a special class of hydrogen bonds called "strong" or "low-barrier" and characterized by great strength, short distances, a low or vanishing barrier to hydrogen transfer, and distinctive features in the NMR spectrum. Although the energy of an ordinary hydrogen bond is ca 5 kcal mol-1, the strength of these hydrogen bonds may be > or = 10 kcal mol-1. The properties of these hydrogen bonds have been investigated by many experimental techniques, as well as by calculation and by correlations among those properties. Although it has been proposed that strong, short, low-barrier hydrogen bonds are important in enzymatic reactions, it is concluded that the evidence for them in small molecules and in biomolecules is inconclusive.
