Ab initio calculations at the SCF and correlated levels with triple-zeta doubly polarized basis sets are reported for several diaminocarbenes. Imidazol-2-ylidene, the prototype of the recently isolated stable carbenes, has a significantly higher singlettriplet splitting than the saturated analogue i

✦ Synopsis
Large scale Hartree-Fock calculations were performed to estimate the thermodynamic stability of the recently proposed spheroidal C,, molecule ("Buckminsterfullerene") relative to a sixty-atom single sheet of graphite. The molecular geometry as well as the ionization potential and electron affinity of the postulated compound were computed. The cohesive energy of the spheroidal C& molecule is computed to be higher than that of a sixty-atom single-layer graphite-like sheet.

The PPP CI molecular-orbital theory for three-dimensional systems has been applied to study the UV spectrum of the truncated icosahedral CeO molecule. We have found that only the one-electron transitions to T,, symmetry (4.2270,4.7498 and 6.5182 eV) have oscillator strengths different from zero. Usi
The electronic states and the bond lengths of the truncated icosahedral C,, molecule have been calculated by the Htickel and Coulson-Golebiewski self-consistent Htickel methods. C,, has a stable closed shell with a rather big energy gap ( = 0.847 p) between the HOMO and the LUMO. We have obtained tw
The molecular geometries and electronic structures of phenanthrene and anthracene in the gas phase were studied by using an ab initio molecular orbital method at the HF and MP2 levels with the 6-31G\* basis set. Normal-mode vibrational analyses were performed at the HF/6-31G\* level. The standard th
