Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Structure elucidation</bold>: The IR spectrum of the protonated disilane Si₂H₇⁺ has been derived by resonant IR photodissociation spectroscopy of weakly bound Si₂H₇⁺⋅Ne clusters (see picture). Analysis of the spectra provides the first characterization of this fundamental polysilane cation and direct evidence for the nonlinear SiHSi proton bridge with a three‐center two‐electron bond.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1p8rs66m" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
