We report on measurements of second virial coefficients of all fluorinated methane compounds CH4−xFx (x = 0–4) in the temperature range from 296 K to 463 K and of second interaction virial coefficients of all their binary mixtures. Most of the mixtures deviate strongly from the behaviour of ideal mixtures, the most extreme example being the mixture CH3F–CHF3, where the interaction virial coefficient is remarkably more negative than the virial coefficients of both components. Arguments that allow overall qualitative understanding of this behaviour are presented.

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.
