The electronic structure of conjugated systems. VI
Abstract
This part reconsiders the previously neglected non-orthogonality of atomic orbitals. New generalized definitions of fractional bond order and charge distribution are introduced, and it is shown that under certain conditions, which are satisfied by most conjugated hydro-carbons, the overlap factor is completely irrelevant in calculating bond orders and charges. For heteromolecules this is not the case, and substantial changes may sometimes be made by its inclusion. The various polarizability coefficients introduced in earlier papers are always affected, but numerical results suggest that these changes are not very large.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
