Abstract
Nuclear quadrupole resonances of 79Br and 81Br have been observed in both ZnBr2 and PbBr2 at 77, 195 and 298 K. For ZnBr2 three closely spaced lines at 81.425, 83.100 and 84.137 MHz (81Br, 77 K) of relative intensities 1 : 2 : 1 are in accord with three non-equivalent lattice sites of space group I41/acd. For PbBr2 two lines observed at 20.669 and 27.824 MHz (81Br, 77 K), consistent with space group P bnm, have been assigned to their respective lattice sites on the basis of point-charge model calculations.Keywords
