The Franck-Condon principle governing molecular electronic transitions is utilized tostudy heavy-quark hadron decays. This provides a direct assessment of the wavefunction of theparent hadron if the momentum distribution of the open-flavor decay products is measured. Model-independent results include an experimental distinction between quarkonium and exotica (hybrids,tetraquarks...), an off-plane correlator signature for tetraquarks and a direct probe of the sea quarkorbital wavefunction relevant in the discussion of 3 S1 or 3 P0 decay mechanisms.
