Cosolvent Effects on Solute–Solvent Hydrogen-Bond Dynamics: Ultrafast 2D IR Investigations

Kashid, Somnath; Jin, Geun Young; Bagchi, Sayan; Kim, Yung Sam (The Journal of Physical Chemistry B, 2015-11-24)

Cosolvents strongly influence the solute–solvent interactions of biomolecules in aqueous environments and have profound effects on the stability and activity of several proteins and enzymes. Experimental studies have ...
Does Viscosity Drive the Dynamics in an Alcohol-Based Deep Eutectic Solvent?

Chatterjee, Srijan; Deshmukh, Samadhan; Bagchi, Sayan (The Journal of Physical Chemistry B, 2022-10-06)

Deep eutectic solvents, consisting of heterogeneous nanodomains of hydrogen-bonded networks, have evolved into a range of viscous fluids that find applications in several fields. As viscosity is known to influence the ...
Hydrocarbon Chain-Length Dependence of Solvation Dynamics in Alcohol-Based Deep Eutectic Solvents: A Two-Dimensional Infrared Spectroscopic Investigation

Chatterjee, Srijan; Ghosh, Deborin; Haldar, Tapas; Deb, Pranab; Sakpal, Sushil; Deshmukh, Samadhan; Kashid, Somnath; Bagchi, Sayan (The Journal of Physical Chemistry B, 2019-10-14)

Deep eutectic solvents (DESs) have gained popularity in recent years as an environmentally benign, inexpensive alternative to organic solvents for diverse applications in chemistry and biology. Among them, alcohol-based ...
Impact of water addition on fluctuation dynamics in viscous solvents with varied heterogeneity: A 2D IR spectroscopic study

Chowdhury, Tubai; Ghosh, Sucheta; Pathania, Akhil; Kore, Shivshankar; Mon, Akhil B; Chatterjee, Srijan; Deshmukh, Samadhan (Chemical Physics Impact, 2023-10-05)

The addition of cosolvent, such as water, influences the overall fluctuation dynamics as sensed by the probe. It is crucial to unravel the fluctuation dynamics when water is added, particularly in viscous solvents with ...
Ligand Dynamics Time Scales Identify the Surface–Ligand Interactions in Thiocyanate-Capped Cadmium Sulfide Nanocrystals

Deshmukh, Samadhan; Chatterjee, Srijan; Ghosh, Deborin; Bagchi, Sayan (The Journal of Physical Chemistry Letters, 2022-03-30)

The nanocrystal surface, which acts as an interface between the semiconductor lattice and the capping ligands, plays a significant role in the attractive photophysical properties of semiconductor nanocrystals for use in a ...
Solvation structure and dynamics of a small ion in an organic electrolyte

Kore, Shivshankar; Sahoo, Rudhi Ranjan; Santra, Binit; Sarkar, Archishman; Chowdhury, Tubai; Deshmukh, Samadhan; Hazarika, Sulagna; Chatterjee, Srijan; Bagchi, Sayan (Journal of Photochemistry and Photobiology A: Chemistry, 2022-03-09)

Organic carbonates are commonly used as electrolytes in commercial lithium-ion batteries. A detailed interpretation of the solvation structure and dynamics of the electrolyte around ions is necessary to understand the ...
Transition of a Deep Eutectic Solution to Aqueous Solution: A Dynamical Perspective of the Dissolved Solute

Sakpal, Sushil; Deshmukh, Samadhan; Chatterjee, Srijan; Ghosh, Deborin; Bagchi, Sayan (The Journal of Physical Chemistry Letters, 2021-09-07)

Disruption of the deep eutectic solvent (DES) nanostructure around the dissolved solute upon addition of water is investigated by polarization-selective two-dimensional infrared spectroscopy and molecular dynamics simulations. ...
Two-Dimensional Infrared Spectroscopy Reveals Cosolvent-Composition-Dependent Crossover in Intermolecular Hydrogen-Bond Dynamics

Kashid, Somnath; Geun, Young Jin; Chakrabarty, Suman; Kim, Yung Sam; Bag, Sayan (The Journal of Physical Chemistry Letters, 2017-03-22)

Cosolvents have versatile composition-dependent applications in chemistry and biology. The simultaneous presence of hydrophobic and hydrophilic groups in dimethyl sulfoxide (DMSO), an industrially important amphiphilic ...
