Abstract

The theory of energy shifts in mirror-image molecules arising from parity nonconserving weak neutral currents is developed. Its connection with the theory of optical activity is discussed. In order to demonstrate the existence of the energy shift, which produces an energy difference between an optically active molecule and its mirror image, an exact calculation is performed for a simple one-electron model (the Condon model). Then approximate LCAO-MO calculations are performed on two specific molecules, twisted ethylene and A-nor-2-thiacholestane, in order to obtain more reliable order-of-magnitude estimates of the energy shifts than available previously. According to our calculations, the former molecule has an energy shift two orders of magnitude larger than the latter, but both molecules have energy shifts which are appreciably smaller than the previous estimates.

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.
