Ozone reaction with singlet molecular oxygen

Uemi, M., Ronsein, G.E., Miyamoto, S., Medeiros, M.H., Di Mascio, P. (2009) Generation of cholesterol carboxyal-dehyde by the reaction of singlet molecular oxygen [02 (IDelta(g))] as well as ozone with cholesterol. Chem. Res. Toxicol, 22(5), 815-884. 

It has been suggested23,59 that ground-state atomic oxygen, produced in discharges or thermal reactions, can react with ozone to produce a singlet molecular oxygen product... 

Where RH - the monomer units of polymer. Reaction can be triggered by physical factors such as ultraviolet and ionizing radiation, heat, ultrasound, or mechanical treatment chemical factors, such as catalysis, a direct reaction with molecular, singlet or atomic oxygen and ozone. However, initiation by direct interaction of molecular oxygen with the polymer, leads to detachment of a hydrogen atom, was unlikely, because it is endothermic reaction, enthalpy is 126-189 kj/mol (Chan J.H., Balke S.T., 1997). Often, the birth of the chain portrayed as the bimolecular interaction of oxygen with the monomer units of polymer...
