Benzyl and tropyl in charge : Electronic spectra of mass‐selected benzylium (Bz + ) and tropylium (Tr + ) cations embedded in solid neon are reported for the first time. They reveal a weak (1) 1 B 1 ← ${{{\rm{\tilde {\rm X$ 1 A 1 visible (see picture) and a much stronger (1) 1 A 1 ← ${{{\rm{\tilde {\rm X$ 1 A 1 ultraviolet transition for Bz + ( C 2 v symmetry). The lowest dipole‐allowed 1 A′′ 2 ← ${{{\rm{\tilde {\rm X$ 1 A′ 1 absorption in the ultraviolet region for Tr + ( D 7 h ) is also observed.
