AI Reconstructs Molecules from Exploding Fragments

Scientists at the SLAC National Accelerator Laboratory and European XFEL have developed a generative AI model to reconstruct 3D molecular structures ^[1][2]. The system analyzes the movement of ions after a molecule is blasted apart by high-powered X-rays ^[1]. This technique, known as Coulomb explosion imaging, captures detailed snapshots of molecules during chemical reactions ^[2]. The AI model tracks scattered fragments to rebuild the original shape of the molecule ^[1]. This process allows researchers to observe how molecules change and interact in real time ^[2]. The breakthrough provides a new tool for studying complex molecular dynamics and reaction pathways ^[1][2].
