(seechemical bond) holding the hydrogen atoms are drawn together slightly, resulting in the angle of 105° between these bonds. This arrangement results in a polar molecule, since there is a net negative charge toward the oxygen end (the apex) of the V-shaped molecule and a net positive ...
From a molecular geometry perspective, the hybridization of the central atom in H2O leads to a bent or V-shaped structure. This is because the repulsion between the lone pair and the bonding pairs of electrons pushes the hydrogen atoms closer together, resulting in a smaller bond angle. From ...

The valence-bond structures considered properly described the change in the molecular system as the hydrogen atoms were individually removed to infinity. The calculated equilibrium geometry for the H 2 O molecule has an O-H bond length of 1.83 Bohrs and an HOH bond angle of 106.5°. With 49...
The average hydrogen-bond angles of liquid-like AADDs water molecules is 162° in the H+(H2O)21 cluster, which is very close to the average angle of 158o in liquid water, indicating that the AADDs water molecules are less confined, and its hydrogen-bond strength with the partners is ...
These calculations succeed in reproducing the ground state equilibrium bond angle, 41 42 capture the degeneracy of the X~ and A~ states at linear geometries, and highlight the small 43 44 45 equilibrium bond angle of the B~ 2B1 state (∠HOH ~54°) and the CI between the B~ and A~ ...

As noted before, we focus these correlations on the N–H⋯O H-bond, and care should be taken to extrapolate these results to other types of H-bonds. Fig. 1 shows the correlation between the intermolecular distance R(N–H⋯O) and the hydrogen bond angle ∠(N–H⋯O). A linear ...
The scan was achieved using a variation in the angle Δθ of the incidence of the pump beam, provided by the rotation of a dielectric mirror installed on the computer controlled support (M2 in Fig. 1 (a)). The displacement Δx of the pump beam on the surface of Fe is the following:...
An analysis of the through-bond interaction using the localized molecular orbitals—IV: Long-range proton hyperfine coupling in exo- and endo-hydrogens in bicyclo[2.1.1]hex-5-yl radical The INDO calculations were performed on bicyclo[2.1.1]hex-5-yl radical. From these calculations, it was co...
