Hydrogen bonding (H-bonding) is an important and very general phenomenon. H-bonding is part of the basis of life in DNA, key in controlling the properties of water and ice, and critical to modern applications such as crystal engineering, catalysis applications, pharmaceutical and agrochemical deve...
Role of quantum nuclei and local fields in the x-ray absorption spectra of water and ice In particular, the intensity of the pre-edge feature, a spectral signature of broken and distorted hydrogen bonds, is accurately reproduced, in water and ice, only when quantum nuclei are considered. The...
the H2S dimer is known to be hydrogen bonded. However, its hydrogen-bonded geometry shows differences from that of the H2O dimer, which can be understood by considering the monomer structures. The S-H bonds in H2S are nearly perpendicular, with an HSH angle of ...
Why do nonmetals form covalent bonds? What intermolecular force is responsible for the fact that ice is less dense than liquid water? Why is metallic bonding strong? How does hydrogen bonds affect polarity in the functional group? Explain the following using proper principles of intermolecular ...
Ice IV, made metastably at pressures of about 4 to 5.5 kb, has a structure based on a rhombohedral unit cell of dimensionsaR= 760±1 pm, α = 70.1±0.2°, ... H Engelhardt,B Kamb - 《Journal of Chemical Physics》 被引量: 83发表: 1981年 Hydrogen bonds from water molecules to aro...
It was found that in the former case, there is an enhanced number of water monomers without H bonds, that the numbers of 2- and 3-bonded molecules are smaller, and the number of 4-bonded molecules is larger than in the latter case. 展开 关键词:...
Liquid water, a system intensively studied in the search for a rationale for its unique properties and many unsolved anomalies1, has been long unanimously believed to have a dominating structure with a symmetric "ice-like" tetrahedral coordination assured by the two-donor and two-acceptor bonding ...
Hydrogen bonding (HB) in supercritical water (SCW) is much less extensive than in water at ambient conditions. Still, it plays an important role in the structural and dynamic properties of SCW and its capacity as a solvent. In order to deal with the HB i
bonds and thereby widens the bandgap.27Beyond the goal of developing advanced proton-conducting electrolytes, proton incorporation into variable valence oxides provides a means of precise control of electronic and magnetic properties.34The electrochemical synaptic device illustrated in Figure1b exploits this...
