E.s.r. evidence for the photo-formation of N2O? and the electron transfer from it to O2 at 77 K on titanium oxide grafted onto porous vycor glass

E.s.r. studies have shown that u.v. irradiation of titanium oxide grafted onto porous Vycor glass in the presence of N2O leads to formation of N2O– anion radicals, their electrons being easily transferred to added O2 molecules to produce O2– anion radicals even at 77 K.
