The detectabilities and some parameters of electron + aromatic hydrocarbon reactions were investigated in a constant-current, variable-frequency electron-capture detector. It was found that lower alkylbenzenes give weak signals in the detector, polymethylbenzenes, styrene, indene, naphthalenes and biphenyl exhibit medium responses, whereas the response factors of aromatics with three rings and those of diphenylthylene, diphenylacetalyne and azulene are relativity high. On the basis of the temperature dependence of the response factors the electron affinities and the electron absorption and desorption rate constants were determined for many aromatics, and the magnitudes of the response factors are discussed.
