DIELECTRIC DISPERSION IN CONDENSED PHASES OF MOLECULES EXHIBITING INTERNAL ROTATION

Abstract

An apparatus was designed and is in the process of assembly for the measurement of transmission and reflection spectra of liquids and solutions in the frequency interval between 8.2 an 12.4 kmc. Attenuation and the reflection coefficient are measured as a continuous function of frequency and will permit calculation of the imaginary and the real parts, respectively, of the complex dielectric constant. A Varian VA-161 backward-wave oscillator, coupled to the waveguide system with a broad-band ferrite isolator, provides a continuous source of frequencies between 8.2 and 12.4 kmc. A microwave reflectometer, employing 2 multi-hole directional couplers, comprises the basic circuit for the continuous frequency measurement of the reflection coefficient.
