Abstract

Velocity-map ion imaging (VMI) has been used to study the angular distribution of the NO fragment generated in the photodissociation of NO2 at a variety of photolysis wavelengths. Images were recorded for the channels NO 2Π1/2 (v″NO = 0, J″NO= 3/2, 11/2 and 21/2) + O (3P2,1), for excitation energies ranging from the onset (Eavl/hc = 0 cm−1) to Eavl/hc ≃ 900 cm−1. The angular anisotropy parameter β was obtained as a function of available energy. Photofragment multiphoton ionization (PHOMPI) spectra were also recorded in the energy range Eavl/hc = 0–300 cm−1 for each of these channels. Large fluctuations of β as a function of Eavl were found in all observed dissociation channels. These variations are discussed in terms of the lifetimes of the originally photoexcited overlapping resonances in the à 2B2 state of NO2, the dynamics of which are strongly influenced by nonadiabatic coupling with the 2A1 state. The potential use of this photolysis process for production of cold oxygen atoms is discussed.

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.
