Singlet oxygen - Wikipedia
Singlet oxygen, systematically named dioxygen(singlet) and dioxidene, is a gaseous inorganic chemical with the formula O=O (also written as 1 [O 2] or 1 O 2), which is in a quantum state where all electrons are spin paired. It is kinetically unstable at ambient temperature, but the rate of …
12.3: The Chemistry and Biochemistry of Dioxygen
Singlet oxygen can be made from triplet oxygen by photoexcitation. Alternatively, it can be made from triplet oxygen through collision with an excited molecule which relaxes to the ground state after a radiationless transfer of energy to triplet oxygen to form reactive singlet oxygen.
Atomic oxygen | O | CID 159832 - PubChem
Singlet Oxygen is an inorganic gas in which all of the electrons are spin paired and the lowest excited state of the diatomic oxygen molecule, with potential cytotoxic activity. Singlet oxygen (sO2) is highly reactive with organic compounds and contributes to the photodegradation of …
Allotropes of oxygen - Wikipedia
Singlet oxygen is the common name used for the two metastable states of molecular oxygen (O 2) with higher energy than the ground state triplet oxygen. Because of the differences in their electron shells, singlet oxygen has different chemical and physical properties than triplet oxygen, including absorbing and emitting light at different ...
4.1: Introduction - Chemistry LibreTexts
Singlet oxygen undergoes reactions that are different from the usual triplet oxygen and it is considered a reactive oxygen species; it is linked to LDL cholesterol oxidation and cardiovascular damage, for example.

Singlet oxygen is the common name used for the two metastable states of molecular oxygen (O 2) with higher energy than the ground state triplet oxygen. The energy difference between the lowest energy of O 2 in the singlet state and the lowest energy in the triplet state is about 3625 kelvin (T e (a¹Δ g - X³Σ g - ) = 7918.1 cm -1 .)

Singlet oxygen is an excited form of oxygen. Oxygen normally has two unpaired electrons in its outermost orbital. Upon receiving this exitation, the two electrons occupy a single molecular orbital. Two singlet oxygens go to the ground state by a two molecule, one photon transition.
