Abstract

original image

The gas-phase infrared spectrum of the adamantane radical cation, C10H16+, 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 2A1 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 C10H16+ in hydrocarbon plasmas, including the interstellar medium.
