Article abstract of DOI:10.1002/oms.1210200210

Several polychlorinated phenoxyphenols with three to nine chlorine atoms were examined as their methyl ethers by electron capture negative ion and positive ion chemical ionization and electron impact mass spectrometry.In chemical ionization studies methane, hydrogen, nitrogen, helium and argon were used as reagent gases.Selected compounds were also examined with deuteriomethane, ammonia and deuterioammonia as reagent gases.Utilization of chemical ionization spectra in conjunction with electron impact spectra provides substantial structural information about these compounds.Chemical ionization spectra provide information about chlorine atom substitution.The position of phenoxy substitution can be established from electron capture negative ion and positive ion spectra.
