NWHClI: a small and compact chiral molecule with large parity-violation effects in the vibrational spectrum.

Small but mighty: An unprecedented large parity-violation energy difference of 0.7 Hz for the N-W stretching frequency of N≡WHClI, which conveniently lies in the CO(2) laser frequency range, is predicted from relativistic density functional theory. This result could lead to the first successful detection of such effects in chiral molecules.
