“…• radical, whereas introduction of the chlorine atoms (two of them in conjugated position to the free radical center) will further stabilize the radical 20 and thus lower the AE of the Ar-O-CO + ion. Consequently, while route (b) is visible but minor in fragmentation of the unsubstituted salicylate (Scheme 4), it is the main route of fragmentation of ID647 (Scheme 5).…”

Analyses of chlorinated aromatic contaminants in industrially polluted sediments of the Kymijoki River, SouthEast Finland, were extended to the search of previously unknown pollutants by gas chromatography/mass spectrometry. In the fraction of persistent organochlorines, a series of substances were identified as octa-to tetra-chlorinated phenyl esters of 2-hydroxybenzoic acids (most probably all polychlorinated phenyl salicylates). All their mass spectra were previously unknown and interpreted by fragmentation rules, appearance energy calculations and simulation.

This paper reports a study of resonant dissociative electron attachment (DEA) to the phenol, chlorobenzene, p-, m-, and o-chlorophenol molecules. On the basis of spectroscopic and thermochemical approaches the resonant states of the molecular negative ions (NIs) and the structures of some dissociative decay products are assigned. In the electron energy range up to 3 eV, DEA processes are determined by the two 2[pi*]-shape resonances resulting mainly in formation of [M-H]- and/or Cl- ions. At higher electron energies the energy correlation between peaks in the negative ion effective yield curves and bands of UV spectra allowed identification of the core-excited resonances. The peculiarities of Cl- ion formation and the vibrational fine structure on the effective yield curves of the [M-H]- ions are discussed. The mass spectrometric procedures for measurement of relative cross sections for NI formation are described.
