Abstract

Photodetachment-photoelectron spectra of HS2− and DS2− are presented. The obtained electron affinities (EA (HS2) = 1.916 ± 0.015 eV and EA (DS2) = 1.918 ± 0.015 eV) are in good agreement with earlier results (S. Moran and G. B. Ellison, J. Phys. Chem., 1988, 92, 1794). Photodetachment into the neutral ground state of the radicals HS2 and DS2 leads to excitation of the S–S stretching mode, whereas photodetachment into the first excited state causes a S–S–H bending and a weak S–H stretching motion. Additionally, weak peaks of S2 were observed in the spectra of HS2 and DS2, leading to the conclusion that photodetachment with 2.77 eV (448 nm) causes dissociation of HS2− and DS2− into S2− and H/D. Taking 2.77 eV as an upper limit for D0(S2−–H) a lower limit for ΔfH0(HS2 (g)) of 100.8 kJ mol−1 is obtained which is an improvement on the literature value of 107.145 ± 10.46 kJ mol−1.

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.
