Does viscosity drive the dynamics in deep eutectic solvents? Our recent 2DIR paper at @JPhysChem reveals that a dissolved solute senses a pocket-specific local viscosity, and not the bulk viscosity. @bagchilab @csir_ncl @serbonline @Srijan_chatt tinyurl.com/bdzmwv93

Want to know how deep eutectic solvents (DES) behave in the presence of added water? @bagchilab at @csir_ncl uses polarization-selective 2D IR spectroscopy to probe the transition from "water in DES" to "DES in water" @JPhysChem @sayanbagchi pubs.acs.org/doi/10.1021/ac…
Polarization-selective 𝟐𝐃 𝐈𝐑 𝐬𝐩𝐞𝐜𝐭𝐫𝐬𝐜𝐨𝐩𝐲 can sense the transition from 𝐰𝐚𝐭𝐞𝐫 𝐢𝐧 𝐃𝐄𝐒 to 𝐃𝐄𝐒 𝐢𝐧 𝐰𝐚𝐭𝐞𝐫. DES stands for deep #eutectic #solvents. #Solvation #dynamics probes changes in dynamic heterogeneity around the solute.
