Abstract

We have studied the other unit which is partial element in fullerene $C_{90}$. The energy of the higher fullerene increased by 5.6 kcal/mol for each $1.0{\beta}$ of planarity for the other units and increased by 11.0 kcal/mol for each $2C_1$ other unit at RHF/AM1 method. Therefore, we have known that the stable $C_{90}$ isomer do not have $C_1$ unit in other unit and have small planarity. The confirmable $C_{90}$ isomers by experiment satisfies these two conditions.
