Abstract

The energy of parity-violation due to weak-nuclear interactions between molecular electrons and nucleons associated with three molecules that participate in highly enantioselective autocatalytic reactions is estimated with ab initio techniques. The molecules, derivatives of ( S)-5-pyrimidyl alkanol, are found to have very small parity-violation energy. Although our results are not conclusive, the computed parity-violation energy is not expected to have any effect on the direction of spontaneous symmetry breaking reported in the literature and leading to a preferential formation of the ( S) form.
