Description
Summary:The complex fine structure in the Raman spectrum of the quasi-one-dimensional solid (Pt(C{sub 2}H{sub 8}N{sub 2}){sub 2})(Pt(C{sub 2}H{sub 8}N{sub 2}){sub 2}Cl{sub 2})(ClO{sub 4}){sub 4} is shown, through studies of isotopically enriched materials and lattice-dynamics calculations, to originate from vibrational modes strongly localized by the positional disorder of the two naturally occurring Cl isotopes, making this an elegant example of a real material displaying vibrational localization in one dimension. The modes responsible for the observed features reside on short chain segments defined by a few statistically favored sequences of isotopes.
