β¦ Synopsis
A new ring-stacking model is proposed for preferential generation of C6o with lh symmetry and C7o with Dsh symmetry in carbon soot. The model is constructed on the basis of the following two assumptions: ( 1 ) A carbon closed cage (fullerene) is formed by a sequential stacking with appropriate numbers and combinations of only even-numbered carbon tings. (2) The intermediates, as well as the final closed cages, consist of only hexagons and pentagons with no adjacent pentagons.
