The hydrogen atoms attracted to nonbonding
electron pairs on the oxygen atoms of other water molecules form hydrogen bonds [1-3],
This is because, the quaternization involves the nonbonding
electron in the bonding, thereby lowers the energy.
Hirano, "Conformational analysis of 1,2-dimethoxyethane by ab initio molecular orbital and molecular mechanics calculations: stabilization of the TGG' rotamer by the 1,5 C[H.sub.3]/O nonbonding
attractive interaction," The Journal of Physical Chemistry, vol.
The increase in inhibition efficiency with concentration may be due to the adsorption of caffeine onto the aluminium surface through nonbonding
electron pairs of nitrogen and oxygen atoms as well as the [pi]-electrons of the aromatic rings.
The band around 322 nm is due to naI* transition of the nonbonding
electrons present on the nitrogen of the -C=N in the free ligand.
(6) The RDG analysis shows extended regions of nonbonding
interaction between PVA and the inorganic moiety (Figure 2, colored in green.
Absorption at 290 nm was assigned to charge transfer from the nonbonding
orbital of chloride ions to half-filled d-orbitals of cobalt (II) .
More specifically, molecules containing [pi]-electrons or nonbonding
electrons (n-electrons) can absorb the energy in the form of ultraviolent or visible light to excite these electrons to higher antibonding molecular orbitals.
Similarly, the nonbonding
electrons on the methoxido oxygen were delocalized into Rydberg orbitals of the vanadium ion with the following interaction energies: 7.46 and 1.09kcal/mol for LP(1)O6 [right arrow] [RY.sup.*](2)V and LP(1)O6 [right arrow] [RY.sup.*](5)V, respectively.
10 [Angstrom] cutoff was applied to treat nonbonding
Even more remarkable is the ability to look inside the part wall to see voids in gas-assist parts, weld lines, glass distribution and orientation, integrity of barrier layers, and bonding or nonbonding
of different materials in coinjected or overmolded parts.
