Solvent-induced frequency shifts in the infrared spectrum of acetone in organic solvents
文献信息
The solvent induced frequency shifts observed in the infrared spectrum of acetone as a dilute solute are reported for 23 organic solvents, both polar and non-polar. Both the C2O stretching frequency and the asymmetric stretch of the molecular skeleton show strong correlations with the acceptor number of the solvent, a measure of its Lewis acidity. A detailed study of the absorption in the 1715 cm-1 region for acetone–carbon tetrachloride and acetone–nitrobenzene mixtures reveals the presence of three bands, one due to the acetone monomer and two due to dimers. These data are analyzed to obtain estimates of the dimerization equilibrium constant.

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.
