  • Association–Dissociation Dynamics of Ionic Electrolytes in Low Dielectric Medium 
    Ghosh, Deborin; Sakpal, Sushil; Chatterjee, Srijan; Deshmukh, Samadhan; Kwon, Hyejin; Kim, Yung Sam; Bagchi, Sayan (The Journal of Physical Chemistry B, 2021-12-27)
    Ionic electrolytes are known to form various complexes which exist in dynamic equilibrium in a low dielectric medium. However, structural characterization of these complexes has always posed a great challenge to the ...
  • The Curious Case of Aqueous Warfarin: Structural Isomers or Distinct Excited States? 
    Sakpal, Sushil; Ghosh, Deborin; Manae, Meghna; Hazra, Anirban; Bagchi, Sayan (The Journal of Physical Chemistry B, 2021-03-17)
    Warfarin is a potent anti-coagulant drug and is on the World Health Organization’s List of Essential Medicines. Additionally, it displays fluorescence enhancement upon binding to human serum albumin, making warfarin a ...
  • Evidence of an nN(amide) → π*Ar Interaction in N-Alkyl-N,N′-diacylhydrazines 
    Rai Deka, Jugal Kishore; Sahariah, Biswajit; Sakpal, Sushil; Bar, Arun Kumar; Bagchi, Sayan; Sarma, Bani Kanta (Organic Letters, 2021-05-11)
    1,2-Dibenzoyl-1-tert-butylhydrazine (RH-5849) and related N-alkyl-N,N′-diacylhydrazines are environmentally benign insect growth regulators. Herein, we show that an unusual nN(amide) → π*Ar interaction mediated by a hydrazide ...
  • 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 ...
  • Stabilization of Azapeptides by Namide···H–Namide Hydrogen Bonds 
    Baruah, Kalpita; Sahariah, Biswajit; Sakpal, Sushil; Rai Deka, Jugal Kishore; Bar, Arun Kumar; Bagchi, Sayan; Sarma, Bani Kanta (Organic Letters, 2021-06-01)
    An unusual Namide···H–Namide hydrogen bond (HB) was previously proposed to stabilize the azapeptide β-turns. Herein we provide experimental evidence for the Namide···H–Namide HB and show that this HB endows a stabilization ...
  • 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. ...
