Abstract
In argon matrix isolation, permethylated linear oligosilanes with six or fewer silicon atoms in the chain exhibit nearly identical broad strongly Stokes-shifted fluorescence. As the chain becomes shorter, the emission becomes weaker and its peak red-shifts slightly. We propose that the emission is due to a non-vertical excited state with a single greatly stretched SiSi bond, in which the excitation is localized, and support the proposal by ab initio calculations on Si 2H 6.
