MICROWAVE SPECTRA AND DIELECTRIC PROPERTIES OF VARIOUS AZIDES

Abstract

Design details are presented for an instrument for the measurement of the dielectric constant and loss tangent of small crystals at millimeter wavelengths. A reflection technique is used to determine changes in the resonant frequency and Q of a TM(012)-mode cavity. The instrument, which is now completed, will be used in dielectric studies on alpha and beta-lead azide crystals in the region from 40 to 50 kmc and upward. A Stark-modulated microwave spectrograph is described, along with a phasestabilized klystron source which is to be added to the system. The basic instrument is currently being tested. The Appendix contains a discussion of the infrared spectrum of solid methyl azide, which has been observed over the range 1/400 to 1/4000 cm. Some changes in vibrational assignments for the molecule are suggested. No evidence of hydrogen bonding has been found in the solid.
