The gas‐phase infrared spectrum of the adamantane radical cation, C 10 H 16 + , provides the first spectroscopic characterization of the geometric and electronic structure of this cycloalkane carbocation and direct evidence for the Jahn–Teller distortion in the 2 A 1 ground electronic state. In their Communication on page 4925 ff., O. Dopfer et al. show that the characteristic IR fingerprint may be used for the identification of C 10 H 16 + in hydrocarbon plasmas, including the interstellar medium.
