EPR-Untersuchungen zur Photolyse halogenierter organischer Verbindungen. I. Reine Phasen halogenierter Verbindungen (CBr4, CHBr3, CCl4, CHCl3)

EPR-Investigations on the Photolysis of Halogenated Organic Compounds I. Pure Halogenated Compounds (CBr₄, CHBr₃, CCl₄ and CHCl₃) EPR-spectra of CBr₄, CHBr₃ and CDBr₃, exposed to u.v.-light and γ-rays respectively, are presented. They are discussed and compared with the results of the photolysis of CH₂Br₂, CH₃Br and CCl₄, CHCl₂, CH₂Cl₂ and CH₃Cl. Under stationary conditions at 77K it was possible to identify paramagnetic species like documentclass{article}pagestyle{empty}begin{document}$ {rm CBr}_4,^{_{bar.}} $end{document}, ·CBr₃, ·CH₃, ·C₂H₅, ·CCl₃ and trapped electrons.
