Ion—molecule and radical reactions in condensed layers studied by low temperature field ionization mass spectrometry. Part I. Methanol

Abstract

The ion—molecule and radical reactions induced by field ionization (FI) of methanol in a condensed surface layer are investigated at low emitter temperatures (LT) using isotope labelling and benzene as radical scavenger. No influence of the emitter on the chemical reactions was detected. The results agree with those obtained by radiation chemistry suggesting that LT-FI can be an interesting tool for the investigation of reactions in liquids, since stable and intermediate reaction products are supplied directly to mass spectrometric analysis.
