hydrogen bond

n.
A chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom, especially a nitrogen, oxygen, or fluorine atom, usually of another molecule.

hydrogen bond

n
(Chemistry) a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological molecules

hy′drogen bond`


n.
an electrostatic bond between a hydrogen atom in a covalent bond and an electronegative atom, as oxygen.

hydrogen bond

A chemical bond in which a hydrogen atom that is already bonded to an atom in a molecule forms a second bond with another atom, either in the same molecule or in a different one. The second atom is usually of a type that strongly attracts electrons, such as nitrogen or oxygen.

Experimental details are given in Table-1 while selected bond distances, angles and dihedral angles are given in Table-2 along with H-bond geometries in Table-3.
One approach is to analyze the structures of crystalline solids based on the pairing of H-bond donors and acceptors.
Despite its critical importance, H-bonding is relatively poorly understood, And the iupac definition of the h-bond was changed as recently as 2011- highlighting the relevance of a new means to engage with these fundamental interactions.
lt;=300 MW with, clogP, rotatable bonds, H-bond donors and acceptors all <3.
Methods: Fluoxetine - one H-bond donor, formed ion-associated complexes with tetraphenylborate, tetrakis(4- chlorophenyl)borate and dipicrylamine.
Many of the physical property issues are terminated by DBC hydrogen bond technology in which obstruction within H-Bond is lowered and ideal viscosity is rendered.
These form a set of H-bond donors and acceptors as discussed last month.
That is to say the average H-bond distance decreases slightly with increasing temperature.
To evaluate the effect of simulation time on the force required for H-bond breaking, simulations for two of the runs were extended to 10 ns (set A Figure 4 and set B Figure 5) (21) starting at the points corresponding to the two extensions preceding the point of maximal force.
These modified diamines exhibit reduced reaction rates with NCOs primarily because their NH groups are secondary and therefore can H-bond with the closest carbonyl to form a five-membered ring (Fig.
17 Kcal/mol and this preference can be attributed to the formation of two H-bond: the first is a stronger H-bond which is formed between oxygen of CO[O.
Its main chain carbonyl group is located on the surface and forms an H-bond with the guanidine group of Arg40 in the adjacent [beta] subunit.
