The neutron diffraction analysis of crystals of 2-ethynyladamantan-2-ol (I) provides confirmation of the presence of an unusual OH···π hydrogen bond, together with more common OH···O and CH···O bonds, as proposed previously. Th... Allen, Frank H.,Howard, Judith A. K.,Hoy,...
The debate over the possible role of strong, low-barrier hydrogen bonds in stabilizing reaction intermediates at enzyme active sites has taken place in the absence of an awareness of the upper limits to the strengths of low-barrier hydrogen bonds involving amino acid side chains. Hydrogen bonds ...

The strong hydrogen bonds have been examined by using OPLS and AMBER force fields, and a new water model (WLP) has been suggested. Results on geometries and hydrogen-bond energies have been compared with the corresponding experimental data and quantum mechanical calculations. The OPLS method was ...
The right mix of hydrogen bonds in polymer and cement composites is critical to making strong, tough and ductile infrastructure material, according to Rice University scientists who want to mimic the mechanics of mother-of-pearl and similar natural compo
Using a large flexible Gaussian basis set the calculated hydrogen-bond energy of FHF– is 169 kJ mol–1, which agrees well with a recent gas-phase ion cyclotron resonance determination of 163 kJ mol–1. Reoptimization of the 4-31G and double-zeta basis-set scale factors for F results in...
aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, so H2O can form four hydrogen bonds.[translate]...
