Diffusion Coefficients in Liquids

Diffusion Coefficients in Liquids is a research topic within Spectroscopy. Science Explorer counts 4.1k research works in it since 1952. 9.8% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the measurement, prediction, and modeling of diffusion coefficients of various organic compounds in liquid systems, including aqueous solutions and binary mixtures. The studies cover a wide range of solutes, solvents, and temperatures, and explore factors such as molecular diffusivity, solute-solvent interactions, and the effects of hydrogen bonding. Techniques such as Raman spectroscopy and neural network models are employed to investigate diffusion behavior in different liquid environments.
