要旨

We study the effect of the sugars glucose, trehalose and sorbitol on the reorientation dynamics of water molecules, using polarization-resolved femtosecond infrared spectroscopy. We find that at all sugar concentrations the water dynamics can be described by a single reorientation time constant. With increasing carbohydrate concentration, the water reorientation time constant increases from 2.5 picoseconds to a value of about 15 picoseconds. The slowing down of the water dynamics is strongest for trehalose, followed by glucose and sorbitol.

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.
