Abstract
Dielectric absorption studies of pyrrolidine, piperidine, and dicyclohexylamine in cyclohexane and also in 1,4-dioxan solution have been carried out at microwave frequencies, and the static dielectric constant at 1 Mc/sec has also been determined. For pyrrolidine and piperidine in cyclohexane the dielectric data have been analyzed in terms of contributions from two relaxation times, one of which can be identified with reorientation of the molecule. The magnitude of the other relaxation time seems dependent on a rate process connected with the presence of the dimer.
