Q-switched, laser-induced reactions of thiophene with oxygen were studied as a function of oxygen pressure in the range of 0 to 500 torr. The reaction products identified were co2, so2, h2s, h2o, c2h2, and cos. The product distribution varied with oxygen partial pressure. All products, except so2 reached maximum concentrations at 200 torr of o2, whereas so2 reached a minimum at this pressure. No explanation for the behavior of so2 is given. A possible explanation for the small concentration of c2h2 detected in the reaction mixture was advanced from the standpoint of elemental plasma reactions.
