Zeeman NQR Studies on Powdered Bromine Compounds Having Small η

Abstract

Abstract The Zeeman NQR of 79 Br and 81Br in samples having relatively small r\ was studied on several bromine compounds which were in the powder or polycrystal state. The absorption lines were detected in the integral form by the bridge circuit. When a static magnetic field was applied, the line shapes were broadened and usually two dips appeared symmetrically at both sides of the zero field line. The values of η were estimated from the patterns of the dips. For compounds such as NaBrO3 , however, as expected no dips were observed.
