The solvation dynamics of methanol and acetonitrile in n-heptane /AOT/ methanol and n-heptane/ AOT/acetonitrile reverse micelles have been investigated by picosecond time resolved emission spectroscopy using Coumarin 490 (C-490) as a probe. We have observed a substantially slower dynamics (order of a few ns) of methanol and acetonitrile reverse micelles compared to pure solvents. The solvation time is dependent on the w value (w = [polar solvent]/[AOT]) in the case of methanol reverse micelles but there is little w dependence in the case of acetonitrile reverse micelles. The different w dependence of solvation dynamics of methanol and acetonitrile reverse micelles is explained on the basis of the presence and absence of a hydrogen bonding network.

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.
