THE REACTION OF ATOMIC OXYGEN WITH ACETYLENE. (II) CHEMI-IONIZATION AND CHEMILUMINESCENCE

Abstract

The chemiluminescence and chemi-ionization resulting from the room temperature reaction of atomic oxygen with acetylene were investigated. The absolute intensity of chemiluminescent radiation and the over-all rate of chemi- ion formation were measured and the relative intensities of various individual chemi-ions have been observed with a T.O.F. mass spectrometer. The CH (A to the 2nd power delta - X to the 2nd power pi) system was found to be the most intense feature of the chemiluminescent spectrum. Weak emission from the C2 Swan bands and from the CN violet system was also observed. The intensity of the weak OH emission was found to be consistent with it being produced by reactions with molecular oxygen. The CH emission was shown to arise from a complex series of reactions involving the participation of 3 molecules of acetylene and 2 atoms of oxygen. Two possible mechanisms for its production are discussed.
