摘要

@@1.Introduction Isomer substitutions over [ C60 ] -,[ C70 ] -,[ C72 ] -,[ C74 ] -,[ C76 ] -,[ Q78 ]-and [ C80 ]-fullerene vertices are discussed. The isomer derivation is given on the ba sis of Poya theorem [ 1 ].Symmetry formulas Z,produ cing functions for the determination of the number of chiral and achiral isomer substitutions,isomer distribu tions overp(m) families depending on the number m of substitution places are ascertained. The additive scheme based on the model [ 2 ] for the estimation of gaseous carbon clusters [ C60 ]-[ C100 ] properties is obtained and calculations of△fH°98k,S°98K,C°p298k,△Hcy6n,△fG°298k,lgAp298 gaseous clusters not explored experi mentally are performed.
