Temporary negative ion resonances in benzene and benzene derivatives

New, intense, energy loss resonances below the first excitation potential were discovered in the electron impact excitation spectra of benzene and six of its derivatives. The observed resonances for o-C 6H 4CH 3Cl, C 6H 5Cl, C 6H 5Br and o- 6H 4Cl 2 peak at exactly the same energy as the dissociativ...

Description
Summary:New, intense, energy loss resonances below the first excitation potential were discovered in the electron impact excitation spectra of benzene and six of its derivatives. The observed resonances for o-C 6H 4CH 3Cl, C 6H 5Cl, C 6H 5Br and o- 6H 4Cl 2 peak at exactly the same energy as the dissociative electron capture resonances previously reported for these compounds, suggesting that both resonances proceed via a common temporary negative ion state of the parent molecules.
