NQR Zeeman Effect in 2, 4, 6 Tribromophenol

Abstract

NQR Zeeman effect studies for the ⁷⁹Br isotope of Bromine in 2, 4, 6 Tribromophenol were carried out using single crystals. The orientations of the principal X, Y, and Z field gradient axes for all the zero-splitting loci, obtained in the first axis of rotation, were evaluated. An average value of about 0.04 was assigned for the asymmetry parameter of the electric field gradient tensor at the site of the Bromine nucleus. Percentages of single bond, double bond and ionic characters for each of the three C–Br bonds are calculated.
