Abstract

Abstract: Invited for the cover of this issue are the groups of Elsa Sanchez‐Garcia and Wolfram Sander at the Universität Duisburg‐Essen and the Ruhr‐Universität Bochum. The image depicts the ideas skillfully visualized by Markus Henkel on the shift in equilibrium induced by isotopic labelling. Read the full text of the article at 10.1002/chem.202001202 . Abstract : " Usually, the kinetics of degenerate reactions like the Cope rearrangement of semibullvalenes cannot be followed spectroscopically since there is no driving force in either direction. However, the isotopic labelling allows us to slightly disturb the equilibrium, tipping the scales in favor of the product with the lower zero‐point vibrational energy ."
