Energetic Stabilization of d-Camphor via Weak Neutral Currents

It is shown via a series of numerical tests on the camphor molecule, C10H16O, that the naturally occurringd-enantiomer is energetically stabilized with respect to its mirror image by electroweak force. The calculatedenergy difference between enantiomers, about 1.5310219 hartree, is roughly eight orders of magnitude smallerthan the upper bound suggested by available spectroscopic investigations on the frequency of a spectroscopictransition. However, such a difference is about ten times larger than previous estimates of parity-violatingenergy contributions reported in the literature for other chiral molecules, which makes the idea of electroweakstabilization of one enantiomer more reliable than expected before.
