   The Role of Chirality in State Definition
   Chirality significantly impacts the definition of the chemical state, particularly concerning enantiomeric pairs. While the energy eigenvalues ($En$) for the two mirror-image states are classically degenerate, quantum mechanically they differ by the minuscule Möbius Tunneling Energy ($\Delta E{\mu}$), arising from the slight non-zero expectation value of the [spatial inversion operator](/entries/sp…
