Quadrupolar Study of Barium in Barium Bromide Dihydrate by Proton Magnetic Resonance

Abstract
The Zeeman‐split quadrupolar resonances for Ba137 in BaBr2·2H2O were measured by using coincident enhanced protonresonance as a detector. The principal axes of the electric field gradient were found to be oriented thus: x parallel to b, y parallel to c, and z perpendicular to the bc plane. a, b and c are the crystallographic axes. The asymmetry parameter is 0.73±0.01 and the pure quadrupole resonance frequency is 24.38±0.03 Mc/sec.
