Singlet oxygen (or 1O2) is the common name used for the diamagnetic form of molecular oxygen (O2), which is less stable than the normal triplet oxygen. Because of its unusual properties, singlet oxygen can persist for over an hour at room temperature, depending on the environment. Because of differences in their electron shells, singlet and triplet oxygen differ in their chemical properties. The damaging effects of sunlight on many organic materials (polymers, etc.) are often attributed to the effects of singlet oxygen.
