Nonbonding states

This simple treatment, formulated in a context of molecular bonding, was also what led Cox and Symons (1986) to propose the bond-center site as an explanation for anomalous muonium (Mu ). The location of the muon at the nodal plane of the nonbonding orbital explains the very small hyperfine coupling observed in pSR. Still, the muon is close to the electron, which occupies a nonbonding state on the neighboring semiconductor atoms.

A sequence may form and eventually meet a B sequence, as shown, but in doing so, a free radical, called a soliton, is produced. The soliton is a relatively stable electron with an unpaired spin and is located in a nonbonding state in the energy gap, midway between the conduction and valence bands. It is the presence of these neutral solitons which gives frany-polyacetylene the characteristics of an intrinsic semiconductor with conductivities of 10 to 10 (f2 cm) ... 

However, so far all the applications of the JT effect theory were realized only for chemically bonded systems in their high-symmetry configuration and transition states of chemical reactions. We show here that this is an unnecessary restriction the JT type instability is inherent to all the cases of degeneracy or pseudodegeneracy in molecular systems and condensed matter including nonbonded states in molecule formation from atoms, intermolecular interaction, and chemical reactions. 

Indeed, na = 0, for example, in SF6, determines the maximum value of the magnitude of the coupling CBO element YHa,aa = Yoa,Ha = 2y/PQ, and n = 1 diminishes it by a factor of 2, while the double occupation of cpa(a) gives rise to the nonbonding state corresponding to the separate, decoupled subchannels for each orbital,... 

The visible and near ultra-violet (1-6 eV), and vacuum ultra-violet (4-8.5 eV) spectroscopic studies focus on transitions from the occupied states at the top of the valence band, primarily O 2p tt nonbonding states to the conduction band states, primarily O 2p ir and cr antibonding states that are mixed TM atomic states in the context of SLAC s. These spectra also include intra-d-state d-d transitions between occupied ground states and empty excited states of band edge defects these are not be confused with d-d transitions that terminate in virtual bound resonance antibonding states within the vacuum continuum. In the context of many-electron theory as applied to X-ray measurements, these states are referred to respectively as shake-up and shake-off states. The SE instruments used in these studies were developed by D.E. Aspnes during his research studies at Bell Labs, and more recently at NCSU [4,5].
