摘要: The fragmentation of chlorinated guaiacols (2-methoxyphenols) on electron impact has been studied. most common processes are interpreted and in some cases the small differences between spectra positional isomers explained. In addition to well-known alkyl-oxygen fission (loss methyl radical), metastable ion studies deuterium labelling have indicated several new pathways. characteristic formation [MCH3HCl]+ [MCH3Cl]+· ions. general, however, shown be very similar.
