Structure elucidation : The IR spectrum of the protonated disilane Si 2 H 7 + has been derived by resonant IR photodissociation spectroscopy of weakly bound Si 2 H 7 + ⋅Ne clusters (see picture). Analysis of the spectra provides the first characterization of this fundamental polysilane cation and direct evidence for the nonlinear SiHSi proton bridge with a three‐center two‐electron bond.
