The mass spectra of the bis(trimethylsilyl) esters of maleic and fumaric acids provide a simple and particularly striking example of the influence of stereochemistry on the electron‐impact‐induced fragmentation of organic molecules. The results provide evidence for the structural significance of the m / e 147 ion, which is considerably more intense in the maleate spectrum than in the fumurate spectrum.
