Direct observation of the 7-norbornyl cation was achieved for the first time by spectroscopy in an SbF5 matrix at low temperatures. Ab initio calculations at the highest level and the comparison of calculated and experimental IR spectra suggest that the unsymmetrically bridged structure 1 is the most probable for this cation.
