Chapter 6. Tunnelling and Parity Violation in Chiral and Achiral Molecules: Theory and High-resolution Spectroscopy

Quantum mechanical tunnelling was discovered in 1927 by Friedrich Hund in the context of a discussion of the stereomutation reaction between the enantiomers of chiral molecules. We review here the fundamental new aspects introduced by the discovery of parity violation in 1957 and the subsequent form...
