The experimental results suggest that the behavior of low temperature water can be explained in terms of a systematic evolution of a local hydrogen bond configuration towards the continuous random hydrogen bonding network (CRN) for the amorphous and vitreous ice....
The meaning of HYDROGEN BOND is an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usually another molecule of the same or a different polar su
HYDROGEN bonds play a crucial role in the behaviour of water1–4; their spatial patterns and fluctuations characterize the structure and dynamics of the liquid5–7. The processes of breaking and making hydrogen bonds in the condensed phase can be probed indirectly by a variety of experimental tec...
a, Ab initio simulation of the inelastic and elastic scattering signal change for vOH = 1 in comparison to vOH = 0. The simulation is performed on a single water molecule with OH bond lengths adjusted to the equilibrium length for each vibrational state as predicted in ref. 5 (for...
Extended double zeta Gaussian basis SCF LCAO MO calculations have been performed on various configurations of the linearly hydrogen-bonded water dimer and two of the triplet clusters which occur in both cubic and hexagonal ices. A hydrogen bond energy of −4.72 kcal/mole was found for the dimer...
Hydrogen bond in waterThe most ubiquitous, and perhaps simplest, example of a hydrogen bond is found between water molecules. In a discrete water molecule, water has two hydrogen atoms and one oxygen atom. Two molecules of water can form a hydrogen bond between them. The oxygen of one water...
We report spectroscopic evidence of isomer interconversion in water cluster anions, (H2O)(n)(-), which occurs through the interaction with a benzene molecule. An anion complex composed of (H2O)(6)(-) and benzene, Bz center dot(H2O)(6)(-), is formed via the reaction of (H2O)(6)Ar-...

Hydrogen-bond (H-bond) dynamics in the air-water interface is studied by molecular dynamics simulations. The analysis reveals that the dynamics of breaking and forming hydrogen bonds in the air-water interface is faster than that in bulk water for the polarizable water models. This is in contra...
摘要: An amide macrocycle with a highly preorganised cavity containing both polar and non-polar recognition sites forms stable complexes with cyclic dipeptides in water via amide–amide hydrogen-bonds, NH–π hydrogen-bonds and hydrophobic contacts....
