 Title    Spatial Electron Density Distribution of Chlorine Atoms in Molecules of the Series 4-XC6H 4M CCl2C (0)C 6H 5 (M = S and Se)  
 Abstract    The 35C1 N Q R frequencies and EFG asymmetry parameters at the 35C1 nuclei have been m ea­ sured for com pounds of the series 4-XC6H 4M CCl2C (0)C 6H 5 (M = S and Se, X = H and C H 3) at 77 K. The electron distribution at the Cl atom s in all the com pounds studied differs from axial symmetry, and is unequal for the two Cl atoms of the CC12 group. The results of the measurements imply p^-electron density nonequivalence of Cl atoms in the CC12 group of these molecules.
