Molecular shape. It is the most stable and common allotrope of oxygen. The unusual electron configuration prevents molecular oxygen from reacting directly with many other molecules, which are often in the singlet state. EC Number. At higher temperatures or in the presence of suitable catalysts the reaction proceeds more readily. From Wikipedia, the free encyclopedia. Std molar entropy S o Journal of the American Chemical Society.


  • Triplet oxygen, 3O2, refers to the S = 1 electronic ground state of molecular oxygen (dioxygen). According to molecular orbital theory, the electron configuration of triplet oxygen has two electrons occupying two π molecular orbitals (MOs) of.

    The extra energy required is sufficient to prevent direct reaction at ambient temperatures with all but the most reactive substrates, e. Molecules of triplet oxygen contain two unpaired electrons, making triplet oxygen an unusual example of a stable and commonly encountered diradical. Journal of the American Chemical Society. At higher temperatures or in the presence of suitable catalysts the reaction proceeds more readily.

    For instance, most flammable substances are characterised by an autoignition temperature at which they will undergo combustion in air without an external flame or spark. In accordance with Hund's rulesthey remain unpaired and spin-parallel and account for the paramagnetism of molecular oxygen.
