Zusammenfassung:IT is well known that a solution of oxygen in an organic solvent produces a charge-transfer (CT) spectrum 1–6 , the intensity of which has in some cases been shown to be proportional to the oxygen concentration 2,4,6 . This spectrum is evidently “collisional” in origin, no stable complex being formed between oxygen and the organic compound 3,4 . We have followed the oxygen consumption in a hydrocarbon autoxidation by following the decay of the CT spectrum. The technique is less sensitive than the traditional measurement of oxygen absorption from the gas phase into a vigorously stirred or shaken solution 7,8 , but it has the advantage of being a simpler technique, measuring oxygen consumption in the solution directly and requiring small amounts of materials.
