要旨

We review some conceptual and technical tools that help in the understanding of the global shape of energy distributions in the products of complex-forming three-atom reactions governed by long-range forces. The phase space theory (PST) of chemical reactions is simplified so as to arrive at an analytical expression of the recoil energy distribution in which two major factors of the dynamics appear explicitly. These factors are called the angularexcitation ρ1′ and the diatomicinertialcontribution ρ2′ for physical reasons that are detailed in the paper. In the case of strong angular excitations, a third quantity is shown to play a role, namely, the totalangularmomentumdependenceofthereactionprobability. We also propose a straightforward procedure for estimating the statistical energy partitioning in the context of the previous findings. In this regard, the procedure should help the experimentalist significantly in the search for some of the physical factors influencing his results.

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.
