Photoion-pair dissociation dynamics of polyatomic molecules with synchrotron radiation
Literature Information
Shan Xi Tian
Positive–negative photoion pairs can be formed in the photoexcitation of molecules in the broad energy range from vacuum ultraviolet to soft X-ray. Synchrotron radiation is the most suitable photon source and state-of-the-art mass spectrometry techniques have been successfully applied in the experimental studies of such ion-pair photodissociation dynamics. This perspective will briefly review the recent progress on this topic and provide a general description of the mechanisms of ion-pair photodissociation dynamics of polyatomic molecules. Challenges in the understanding of ion-pair photodissociation in the higher photon energy range are also discussed.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
