Abstract

The Zeeman effect of the nuclear quadrupole resonance has been studied on the 35Cl-nuclei in the racemic α-BHC single crystal at room temperature. The directions of the principal x-, y- and z-axes of the field-gradient tensor at each nucleus have been determined through two runs of measurements of the no-splitting loci of each absorption line. The asymmetry parameters of the field-gradient tensor have also been determined. The C–Cl bonds have been found to be considerably distorted from the directions to be expected from the tetra-hedral bond angles for each carbon atom. The distortion takes place in such a way that the skeleton of each molecule approachs a planar configuration. Since the principal axes show a tendency to satisfy the two-fold symmetry, the distorting force has been attributed mainly to the intramolecular forces, and only partly to the intermolecular forces. The previous assignment of the six absorption lines to the six chlorine atoms in the molecule has thus been confirmed.
