Probing intermolecular interactions in a binary mixture of deep eutectic solvents with DMSO by impulsive stimulated Raman spectroscopy

Abstract

The physicochemical properties of deep eutectic solvents (DESs) can be altered in binary mixture with co-solvents like water, dimethyl sulfoxide (DMSO), etc. due to the synergistic effect of hydrogen bond donors-acceptors (HBDs-HBAs) that arises from the interactions of DESs with (organic) solvents. We investigated the intermolecular interactions of DES (1,3-Propanediol-based) of varying compositions in binary mixture with DMSO and observed the emergence of a new vibrational mode using impulsive stimulated Raman spectroscopy (ISRS). © Anita Publications.
