Arn+H3 ions are produced in a laser vaporization source, and their stability against black-body radiation is tested in an FT-ICR mass spectrometer. Using a magnesium target and hydrogen doped argon as carrier gas, Arn+H3 are formed with n = 1–3 in large quantities and traces of n = 4. Arn+H, n = 1–3 are also present. Both Ar3+H3 and Ar2+H3 are heated by room temperature black-body radiation and decay on a timescale of seconds. The observed rate constants are compared with recently calculated IR spectra. The results are in agreement with the presence of strong IR absorptions around 350 cm−1, which may serve as a fingerprint for the identification of H3+ in solid argon.

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.
