The electron impact mass spectra of some bis-(2-benzothi~lyI)furans and bis-(2-benzothiazolyl)thiophenes have been recorded and the identity of various ions in the mass spectra established. Compounds 1 and 2 present model substances and it is found that their fragmentation pathway is similar to the

A family of 12 (7 saturated and 5 unsaturated) long chain fatty acid N-(2-hydroxyethyl)amides has been investigated by electron ionization (EI) and positive-ion chemical ionization (PICI) mass spectrometry. This paper presents the mass spectra and structures of the main ions obtained by EI and PICI
