Our recent @JPhysChem publication reveals a unique correlation between the peak-frequency of the emission band and the electric field on the nitrile bond in cyano-tryptophan.

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

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

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.
