Hydrogen bonding in water But when the H2O molecules are crowded together in the liquid, these attractive forces exert a very noticeable effect, which we call (somewhat misleadingly) hydrogen bonding. And at temperatures low enough to turn off the disruptive effects of thermal motions, water freez...
Water, hydrogen bonding, and the microwave background. Progress in Physics, 2009, v. 1, L5 - L8.Robitaille P.-M. Water, hydrogen bonding, and the microwave back- ground. Progr. Phys., 2009, v. 2, L5-L8.Robitaille P.M.L. Water, hydrogen bonding and the microwave background. Prog...
Hydrogen-bonding and intra/intermolecular vibrational coupling of water next to a hydrophobic molecule (tert-butyl alcohol, TBA) have been studied by Raman multivariate curve resolution (Raman-MCR) and isotopic dilution spectroscopy. Raman-MCR provides the vibrational spectrum of water pertinent to the...
The hydrogen-bonding properties of water-ethanol of alcoholic beverages and water-ethanol mixtures of the corresponding ethanol contents were examined on the basis of OH proton NMR chemical shifts and the Raman OH stretching spectra of water and ethanol. Japanese shochu, an unaged distilled spirit of...
Hydrogen bonding and percolation in propan-2-ol - Water liquid mixtures: X-ray diffraction experiments and computer simulations propan-2-ol molecule and the well-known TIP4P/2005 water model, were able to provide semi-quantitative descriptions of the measured total structure factors...

A consequence of hydrogen bonding is that hydrogen bonds tend to arrange in a tetrahedron around each water molecule, leading to the well-known crystal structure of snowflakes. In liquid water, the distance between adjacent molecules is larger and the energy of the molecules is high enough that ...
Tags Bonding Hydrogen Hydrogen bonding Molecules Water In summary, when drawing hydrogen bonds between a water molecule and H3PO4 or acetic acid, the hydrogen bond is formed between the polarized hydrogen atom and either the oxygen or hydrogen atom of the compound. In the case of acetic acid,...
Effects of temperature and pressure on the hydrogen-bonding liquid structure of water and formamide are discussed on the basis of X-ray diffraction and NMR... H Ohtaki - 《Journal of Molecular Liquids》 被引量: 43发表: 2003年 The Number of Water-Water Hydrogen Bonds inWater-Tetrahydrofuran an...
Hydrogen Bonding of Water Confined in Mesoporous Silica MCM-41 and SBA-15 Studied by 1H Solid-State NMR (p 5689-5696) The adsorption of water in two mesoporous silica materials with cylindrical pores of uniform diameter, MCM-41 and SBA-15, was studied by 1 H MAS (MAS=magic... Bob,...
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
