Two C60O Structures and Their Relative Stabilities: AM1 Computations

Abstract
C60O is studied by means of the AM1 quantum-chemical method. Full geometry optimization of its Cs and C 2v structures, and harmonic vibrational analysis, are employed in the evaluation of the temperature dependence of their relative stabilities. The C 2v structure remains a minor component of the equilibrium gas-phase mixture even at high temperatures.
