## Abstract The 70 eV negative ion spectra of m‐ and p‐nitrophenyltrimethylsilyl‐ethers and ‐esters show pronounced molecular anions and simple fragmentation patterns. The spectra of the corresponding ortho isomers show peaks produced by rearrangement processes; these reactions have been studied by
