Consider the situation when the electrons that make up a covalent bond spend more time with one atom than with the other. In that case, the atom that has the electrons more often will be slightly more negative than the other atom. The molecule that contains this arrangement is said to be...

Ab initio valence bond calculations are performed for the three lowest states of the oxygen molecule (3危 g , 1螖 g , and 1危+ g ). One objective of the present study was to make a contribution to previous valence bond discussions about the oxygen "double" bond. Further, we study the...
2a) is that two adjacent adsorbed oxygen atoms have the possibility to generate one oxygen molecule by direct *O–*O coupling through the steps Eqs. (11)–(20). The sequence of two *OH adsorption, as well as deprotonation on the M2 dimer, followed the energetically favorable configuration ...
O double bond and frees up 2 CO molecules (Fig. 3(D)). Beside than that, an oxygen molecule is also able to absorb onto a single carbon at zigzag edge forming dioxiranyl complex. The epoxy oxygen plays the same role to disturb and elongate the carbon atom adsorbed to two oxygen atoms...
A kinetic isotope fractionation, in a one-way process, occurs because a molecule containing the lighter isotope has faster translational velocities, allowing it to move preferentially, at higher rates, through the molecules of the medium, leaving behind residue that becomes progressively enriched in ...
2b), respectively, which are longer than the bond length of O2 molecule (1.234 Å). Besides, the Fe–O bond lengths on the O2@FeN4, O2@6, O2@6a, and O2@6I are 1.974, 1.745, 1.724, and 1.731 Å (Fig. 2b), respectively. These results reveal that divacancy defects (6...
17. Using a single-molecule tweezer approach under blue light irradiation, we find that contrary to expectations, oxidative protein damage is facilitated even in its folded state, which conceals a substantial portion of oxidizable atoms. The primary cause of this unusual protein damage appears to ...
Water adsorption isotherms are as in Figure 4.34(a, b) where the shape changes from Type-V (MO and R0) to a hybrid between Type-1 and Type-V for the oxidized carbons indicating little interaction for carbons without oxygen surface groups of the H2O adsorbate molecule with the carbon ...
portion of a removable closure that includes a first container that contains a substance operable to collect a type of molecule contained within a vessel (block1501) and inserting the removable closure into the vessel to cause molecules of the type to chemically react with the substance (block...
