Define Double-bonded. Double-bonded synonyms, Double-bonded pronunciation, Double-bonded translation, English dictionary definition of Double-bonded. covalent bond In a water molecule, each hydrogen atom shares an electron with the oxygen atom . n. A che
It is shown that the valence bond description of the triplet ground state of the oxygen molecule is no less "natural" than that provided by self-consistent field-molecular orbital theory; it is more accurate (unless the self-consistent field result is improved by including configuration ...
studies revealed that the incorporation of the B–O units into the PAHs greatly affected their aromaticity and electronic properties. The synergistic effects of the p-π conjugation, the delocalization of the lone electron pairs of the oxygen atoms as well as the bulky Mes moieties (Mes: 2,4,...

260 Recently, the same authors have found that the polymerization of isobutylene by AlEtCl2 was totally inhibited by the simultaneous presence of a hindered pyridine (to prevent cocatalysis) and of oxygen. This effect was claimed to prove that the mechanism of direct initiation involved the ...

A strong linear relationship was observed between the average double bond equivalence (DBE) and the ratio of carbon to oxygen atoms in oxygenated compounds of dissolved organic matter (DOM). Data were acquired by a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS), equipped ...
