The heat capacities of benzene, hexafluorobenzene and of its 1 : 1 binary mixture adsorbed on NaY zeolite were measured as a function of temperature for 120 K ≤ T ≤ 370 K. They reveal strong loading dependencies and reach extraordinarily high values at intermediate loadings. They are indicative of an energy gap above the ground state or of a state in which soft anharmonic intermolecular modes of the dilute adsorbate are excited. The absence of any phase transitions over a large temperature and coverage range resembles supercritical behaviour, as was predicted in recent theoretical work. At a certain loading, small heat capacity fluctuations reveal subtle structural instabilities which are possibly related to the formation and break-up of aggregates, phenomena which are also expected for matter near the critical point.

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.
