When a molecule interacts chemically with a metal, its orbitals hybridise with metal states to form the new eigenstates of the coupled system. Here, the authors show that in addition to overlap in real space and energy, hybridizing states must fulfil

Identifying reaction pathways is a major challenge in chemistry, and proves particularly difficult for surface reactions. Here the authors show that imaging the molecular orbitals with photoemission tomography provides insight into the structure of s

Molecular orbital tomography, also termed photoemission tomography, which considers the final state as a simple plane wave, has been very successful in describing the photoemisson distribution of large adsorbates on noble metal surfaces. Here, follow

Metalation and self‐metalation reactions of porphyrins on oxide surfaces have recently gained interest. The mechanism of porphyrin self‐metalation on oxides is, however, far from being understood. Herein, we show by a combination of results obtai
