The tetramethylsilane (TMS) chemical ionization (CI) mass spectra of some geometrical isomers of unsaturated dicarboxylic acids, esters and isomeric phthalic acids reveal explicit differences. The (@-acids show an abundant [ M + 73 -CH,I + ion whereas the (a-acids exhibit a strong [ M + 73 -H,OJ + i
