Query: Evidence for a single hydrogen molecule connected by an atomic chain   Stable, single-molecule conducting-bridge configurations are typically
identified from peak structures in a conductance histogram. In previous work on
Pt with H$_2$ at cryogenic temperatures it has been shown that a peak near 1
$G{_0}$ identifies a single molecule Pt-H$_{2}$-Pt bridge. The histogram shows
an additional structure with lower conductance that has not been identified.
Here, we show that it is likely due to a hydrogen decorated Pt chain in contact
with the H$_2$ molecular bridge.
