Abstract

Abstract: We present a brief review of our progress towards measuring parity violation in heavy-metal chiral complexes using mid-IR Ramsey interferometry. We discuss our progress addressing the main challenges, including the development of buffer-gas sources of slow, cold polyatomic molecules, and the frequency-stabilisation of quantum cascade lasers calibrated using primary frequency standards. We report investigations on achiral test species of which promising chiral derivatives have been synthesised.
