摘要

Electronic structures and infrared spectra of C_120XY molecules (X, Y = O, S) and some of the correspond - Ing ions are investigated using PM3 semic - empirical molecu - Lar orbital calculations with full optimization of geometrical Structures. It is found that the energy penalty is about 30- 42 kJ/mol due to introducing a double bond in the five - membered ring except for C_120 O_2 and triplet C_120O_2.
