• The Zeeman effect on <SUP>81</SUP>Br NQR in a single crystal of PBr<SUB>3</SUB>·BBr<SUB>3</SUB> was studied at room temperature. The crystal has an orthorhombic symmetry. The bond angles have been found to be 111.2±0.1° and 111.5±0.1° for Br–B–Br, and 107.0±0.1° and 109.1±0.3° for Br–P–Br. The Br atoms of BBr<SUB>3</SUB> group have relatively large values of η, 0.151±0.004 and 0.120±0.007, while the Br atoms of PBr<SUB>3</SUB> group have small values, 0.025±0.005 and 0.020±0.004. The large η values of Br atoms of BBr<SUB>3</SUB> group are ascribed to the π bonding existing in the B–Br bonds.
