摘要

The combination of Raman spectroscopy with an electrodynamic levitation technique enables insitu and non-invasive investigations of chemical reactions in single microparticles without any disturbing substrate or wall effects. Time-dependent Raman spectra during the condensation of a magnesium chloride microparticle (a model substance of sea-salt particles) with water vapour are reported. The condensation of a MgCl2·6H2O microparticle is also investigated by means of elastic light scattering data. Additionally, the solvation of SO2 and NOx in a MgCl2·6H2O microdroplet is studied by Raman spectroscopy. The uptake of these gases is also determined from elastic light scattering data.

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.
