Study of chemically stable/unstable isomers of the fullerene hydrides, C_(60)H_2 and C_(60)H_4, by use of a generalized Pauling bond order method

摘要

A new index, defined as a generalization of the Pauling bond order, i.e. a ratio between the number of Kekule structures in an isomer of the hydride derivatives C_(60)H_2 and C_(60)_4 to that in the fullerene C_(60) molecule, is proposed. This index is shown to be useful for predicting the chemical stability/instability of the hydride isomers.
