Want to know how deep eutectic solvents (DES) behave in the presence of added water? BagchiLab at CSIR-National Chemical Laboratory uses polarization-selective 2D IR spectroscopy to probe the transition from "water in DES" to "DES in water" The Journal of Physical Chemistry Sayan Bagchi pubs.acs.org/doi/10.1021/ac…

Latest 2DIR work from our group CSIR-National Chemical Laboratory SERB

Does viscosity drive the dynamics in deep eutectic solvents? Our recent 2DIR paper at The Journal of Physical Chemistry reveals that a dissolved solute senses a pocket-specific local viscosity, and not the bulk viscosity.
