Abstract

The free radical ClO and a series of its isoelectronic analogues were studied by a variety of computational methods to determine the configuration of the best Lewis structures. A significant issue in the analysis was that of spin density, which was observed in all cases to be greatest on the chalcogen species and to depend in magnitude on the electronegativity differences between the two atoms. A novel, but unconventional, Lewis structure is proposed to explain the properties of the molecules and the above trend.

  Two systems were evaluated for drawing Lewis structures of period 2 and 3 non-metallic compounds: the octet rule and minimization of formal charge. The test set of molecules consisted of the oxides, halides, oxohalides, oxoanions ,and oxoacids of B, N, O, ...
