TL;DR
This paper investigates how resonance tunneling in molecules influences physical observables, revealing that the resonance spectrum of a rigid molecule predominantly determines tunneling probabilities and related quantum diffusion effects.
Contribution
It provides analytical expressions for tunneling probabilities of rigid molecules and shows the dominance of the rigid molecule's resonance spectrum in tunneling behavior.
Findings

Analytical formulas for tunneling probabilities derived
Quantum diffusion estimations based on resonance spectrum
Abstract
Probabilities of resonant tunneling through a potential barrier are compared for a rigid molecule and an excited molecule. It is shown that the resonance spectrum is mainly governed by the transmission resonance spectrum of the rigid molecule. Analytical expressions for the probability for the tunneling of the rigid molecule through a barrier allow resonance-spectrum-averaged observables, including quantum diffusion, to be estimated.
