Results are presented (relative ion abundances, I.P. and A.P. measurements) to illustrate substituent effects in the massspectra of some γ- and β-substituted methyl butyrates. It is argued that (i)‘sub-decomposition energy’ ions and (ii) competition in the source with fast fragmentation processes are important factors influencing parent/daughter ion ratios, which are then rationalised in terms of the
