Further experimental work, with an improved apparatus, on purified benzene, n-hexane and cyclohexane is reported. The dielectric current at the fundamental frequency is nearly all capacitance current, but it is shown that the dielectric does not behave merely as a non-linear impedance, and must also

is shown that the non-capacitive conduction current through dielectric liquids upon the application of a high alternating field of low audio frequency is space-charge limited. The capacitive current is very nearly all of fundamental frequency; the conduction current a harmonic current components absent from the applied voltage wave. The sum of these 1

The appearance of a characteristic harmonic spectrum in the dielectric current upon application of a high, sinusoidal, field is explained as due to the formation of ionized and/or excited complexes. The field causes the stabilization of short-lived ion clusters initially present, so that a net charg
