Mass Spectrometric Study on Mechanism of Formation of Organic Molecular Ions.(II)

Abstract

The total yield curves of the ion formation from several paraffinic and olefinic hydrocarbons were measured and the decomposition processes are discussed.The C3H5+and C2H3+ions from the n-C4H10+ions may be formed by the hydrogen molecule abstraction reaction.The fbrmation of the C2H4+ions from the iso-C4H10+ions and the cis-2-C4H8+ions may be attributed to the hydrogen migration reaction, while the C2H5+ions from the iso-C4H10+ions and the cis-2-C4H8+ions may be formcd by the rearrangement of hydrogen atoms.The relative yield of the ion formation seems to closelycorrelated with each decomposition process.
