trip·let ox·y·gen

the normal unexcited state of O₂ in the atmosphere, in which the unpaired pair of electrons are so displaced that their magnetic fields are oriented in the same direction, resulting in paramagnetism; each of the heat-generated spectral lines of such oxygen can be split by a magnetic field into a triplet. Compare: singlet oxygen.

The AOPs are based on oxidizing radicals, mainly hydroxyl radicals, while other radicals and active oxygen species such as superoxide radical anions (*O2 ), hydroperoxy radicals (HO2 ), triplet oxygen (3O2) and organic peroxyl radicals (R-O-O*) are also involved [10].
