Multidimensional Large‐Amplitude Motion: Revealing Concurrent Tunneling Pathways in Molecules with Several Internal Rotors

Abstract

Light at the end of the tunnel: Knowledge of the feasible tunneling pathways of a molecule can shed light on the interaction mechanisms that govern its internal dynamics. A combination of rotational spectroscopy, permutation inversion group theory, and multidimensional tunneling formalism has shown that in the series (CH3)3XCl (X=Si, Ge, Sn), electrostatic repulsion is gradually reduced and the chemical bond gains importance.
