 Title    The Zeeman Effect in Quadrupole Double Resonance Spectra: Dependence of the Line Shapes on the Orientation of the Electric Field Gradient Tensor  
 Abstract    The solid effect spectrum of 1,4-dichlorobenzene was recorded at magnetic field strengths in excess of 50 G; at these field strengths Zeeman structure is seen on the 35C1 resonance. Unlike in single resonance experiments, peaks are asymmetric, and the high frequency and low frequency solid effect peaks have not the same shape. Computer calculation o f the solid effect spectrum gives peaks which show the same asymmetry as the experimental spectrum. The simulated line shapes are found to depend on the direction the principal com ponents o f the electric field gradient in the crystal framework and indicate that qyy lies in the plane o f the benzene ring.

 Title    The Breathing Mode of B a B i0 3: Electric Field Gradient and Total Energy Calculations  
 Abstract    We present ab initio full-potential linearized augmented plane wave (LAPW) band structure calculations for BaBiOa. We focus on total energies and electric field gradients at the oxygen site and present results for the breathing mode in the experimentally observed cubic and monoclinic struc­ tures of doped and undoped Baj _JC K xB i0 3.

 Title    Temperature Dependence of Impurity Induced EFG's in Extremely Diluted CuB  
 Abstract    The temperature dependence of impurity induced EFG 's around implanted 12B ions in Cu was measured for two lattice locations using the ß-N M R method. The induced EFG at the nearest neighbouring host atoms decreases with increasing temperature for the case of 12B stopped on interstitial sites, whereas the opposite temperature behaviour was found if 12B is situated in substi­ tutional sites.
