| dc.description.abstract | In this work, the results of dielectric
studies carried out on a number of molecules of the general form y [symbol] x are presented. These molecules have been studied mainly in two forms: as solutions of glassy o-terphenyl, Santovac [superscript R], or atactic polystyrene, and in some cases as the pure compressed solid. It is
in this latter regard that a new technique for the study
of compressed solid preparation has been developed.
Studies were carried out over the frequency range 10[superscript 2] to
10[superscript 5] Hz using a General Radio 1615A Capacitance Bridge.
The experimental data as a function of frequency
at different temperatures were analyzed by computer and
fit to the Eyring rate equation. From this analysis,
activation energy barriers for the observed dielectric
relaxation processes were obtained.
general form are presented.
Molecules studied have been chosen to
correlate such properties as symmetry and electronic and
steric effects to the observed Eyring rate parameters. | |
