The electron ionization mass spectrometric behaviour of melatonin ( N ‐acetyl‐5‐methoxytryptamine) and of a series of its isomers has been studied with the aid of metastable ion experiments. The data show that the different positions of the substituents on the indole ring influence the fragmentation patterns and the relative abundances of the generated ions. © 1998 John Wiley & Sons, Ltd.
