"Trioxidane (also systematically named \u03BC-trioxidanediidodihydrogen), also called hydrogen trioxide or dihydrogen trioxide, is an inorganic compound with the chemical formula H[O]3H (also written as [H(\u03BC-O3)H] or [H2O3]). It is one of the unstable hydrogen polyoxides. In aqueous solutions, trioxidane decomposes to form water and singlet oxygen:400pxThe reverse reaction, the addition of singlet oxygen to water, typically does not occur in part due to the scarcity of singlet oxygen."@en . . .
