The natural bon orbital (NBO) is used to analyze the complexes in terms of charge-transfer energy contributions, which usually increase as the number of O atoms increases. The nature of the interactions has been analyzed using the symmetry-adapted perturbation theory (SAPT) method. The results ...
Bond breaking and bond making in tetraoxygen: analysis of the O2(X3Sigma(g)-) + O2(X3Sigma(g)-) O4 reaction using the electron pair localization function. We study the nature of the electron pairing at the most important critical points of the singlet potential energy surface of the 2O2...
resonance can be regarded as a blending process that spreads double-bond character evenly over the atoms that participate in it. In ozone, for instance, each oxygen-oxygen bond is rendered equivalent by resonance, and each one has a mixture of single-bond and double-bond character (as indicate...
the acceptor site, along with a dipolar orientation of the donor group. The tetrahedral hybridization of oxygen atom is justified by the angle ofR1H⋯Owhich is approximately 180°, while forR2O⋯H, it is 110°. Studies have shown that a decrease in the angle causes reduced stability[9...
no atoms in the compound have anionization energylow enough for electron loss to be likely. In such a case, covalence prevails. As a general rule,covalent bondsare formed between elements lying toward the right in theperiodic table(i.e., the nonmetals). Molecules of identical atoms, such ...
Azoxy bond is an important chemical bond and plays a crucial role in high energy density materials. However, the biosynthetic mechanism of azoxy bond remains enigmatic. Here we report that the azoxy bond biosynthesis of azoxymycins is an enzymatic and no
The relations between the bond energy, bong length and coordination number of Au nanoparticles of 2.75.5 nm have been studied by molecular dynamics simulation method. It is shown that the bonds contracts only in the 1.5 times atomic diameter in the surface, but the bond length are the same ...
of atoms) in certain aromatic systems. The energies of interaction are of an order of magnitude less thancovalent bondsbut greater than the very simple non-directional non-covalent forces (van der Waals or dispersion forces) that occur between all molecules. The unit A is generally oxygen, ...
