Structure of gas‐phase arenium ions : The long‐standing controversy about the geometry of protonated benzene is unambiguously solved by IR spectroscopy. The first high‐resolution gas‐phase spectrum of an arenium ion shows that the σ complex (not the π complex; see picture) is the most stable structure of C 6 H 7 + .
