RESEARCH IN MICROWAVE SPECTROSCOPY

Abstract

Refinements in methods of generation and detection of microwave harmonics at wavelengths down to the 1 - 2 mm region are discussed. Preferred methods are given for selection, shaping, mounting and adjustment of the point- contact diodes used. Other refinements of instrumentation have allowed the measurement of spectra of unstable and involatile molecules with the ability to resolve important hyperfine structures. New microwave spectroscopic measurements included evaluation of precise interatomic distances in fluorine cyanide and chloroacetylene, of electrondistribution properties of cyanamide and diazomethane from nuclear quadrupole effects, and the first precise structural information regarding nitramide in the gas phase. Refined values of centrifugal distortion constants were obtained for several molecules.
