✦ Synopsis

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.

Extensive networks of metastable ions link the major peaks in the electron impact mass spectra of two crown ethers containing 2,6-pyrido units. High-resolution mass measurements and the metastable peaks allow the elucidation of the fragmentation pathways. The spectra are influenced more by the prese
