High Resolution Gigahertz and Terahertz Spectroscopy and Theory of Parity Violation and Tunneling for 1,2-dithiine (C4H4S2) as a Candidate for Measuring the Parity Violating Energy Difference between Enantiomers of Chiral Molecules
Electroweak parity violation leads to a slight energy difference between the enantiomers of chiral molecules (on the order of 100 aeV to 1 feV depending on the molecule) and also to a slow time dependent intramolecular process changing parity with time on the order of ms to ks [1, 2]. Recently we have identi ed 1,2-dithiine (Figure 1) as a possible candidate for measuring ΔpvE using the experimental set up described in [3]. Here we report spectroscopic and theoretical studies needed for the preparation of such experiments on 1,2-dithiine ([4, 5] and references therein). We shall also refer to the evolution of the biomolecular homochirality, which may be related to parity violation [6].
