To hop or to tunnel? The mechanism of electron transfer in peptides is currently the topic of an often heated debate with proponents strongly supporting either electron‐hopping or bridge‐assisted superexchange mechanisms. Experimental and theoretical results to date leave a number of unanswered questions. The Concept article by H.‐B. Kraatz et al. on page 5186 ff. provides an introduction into this debate with a focus on recent results obtained from surface measurements.
