When molecular model systems, such as polycyclic aromatic hydrocarbons, are ionized by ultrashort extreme ultraviolet pulses, their relaxation path proceeds via electron–phonon scattering, linking molecules to typical solid-state matter behaviour.

扎实地看待分子

当分子模型系统（例如多环芳烃）被超短的极端紫外线脉冲电离时，其弛豫路径通过电子-声子散射进行，从而将分子与典型的固态物质行为联系起来。
