We prove the Molecular Conjecture posed by Tay and Whiteley. This implies that a graph G can be realized as an infinitesimally rigid panel-hinge framework in ℝd by mapping each vertex to a rigid panel and each edge to a hinge if and only if $\bigl({d+1 \choose 2}-1\bigr)G$ contains ${d+1\choose2}$ edge-disjoint spanning trees, where $\bigl({d+1 \choose2}-1\bigr)G$ is the graph obtained from G by replacing each edge by $\bigl({d+1\choose2}-1\bigr)$ parallel edges.
