A decade ago a class of molecules was proposed which might have a pair of lowest-energy electronic metastable states. The molecules of this sort are rigid oligomers built of N donor-acceptor pairs as monomers. One of these states (called NEU) is non-polarised; the other one (called ION) differs from

β¦ Synopsis
Ab initio SCF calculations usmg a sllghrly extended basis set have been carried out on the Ion-energy electronic states of methylene. The equilibrwm geometries and enerles of these slates are determined, and potemal curves for each state are obtained.

Low-energy resonances involving the 3~-, l A and 1)2,+ states of NO-have been studied by high-resolution electron scattering integrated over the angular range 60-120 Β° and in the energy range 0.07-1.6 eV. The resonant vibratiohal energies of the 3~-state yield agreement with the NO electron affinity
Much work has been devoted in the past to the spectroscopy of transition metal monohalides, essentially because they are of considerable interest in the fields of catalytic chemistry and high-temperature chemistry. In particular, diatomic compounds of group IIIb atoms, Sc, Y, and La, were the best s
