Water dynamics in water/DMSO binary mixtures.
The dynamics of dimethyl sulfoxide (DMSO)/water solutions with a wide range of water concentrations are studied using polarization selective infrared pump-probe experiments, two-dimensional infrared (2D IR) vibrational echo spectroscopy, optical heterodyne detected optical Kerr effect (OHD-OKE) experiments, and IR absorption spectroscopy. Vibrational population relaxation of the OD stretch of d...
متن کاملHydrogen bonding and the cryoprotective properties of glycerol/water mixtures.
Molecular dynamics simulations and infrared spectroscopy were used to determine the hydrogen bond patterns of glycerol and its mixtures with water. The ability of glycerol/water mixtures to inhibit ice crystallization is linked to the concentration of glycerol and the hydrogen bonding patterns formed by these solutions. At low glycerol concentrations, sufficient amounts of bulk-like water exist...
متن کاملMolecular dynamics studies on the denaturation of polyalanine in the presence of guanidinium chloride at low concentration
Molecular dynamic simulation is a powerful method that monitors all variations in the atomic level in explicit solvent. By this method we can calculate many chemical and biochemical properties of large scale biological systems. In this work all-atom molecular dynamics simulation of polyalanine (PA) was investigated in the presence of 0.224, 0.448, 0.673, 0.897 and 1.122 M of guanidinium chlorid...
متن کاملSolvation shell dynamics of Na+ and Cl- ion pairs in selected water-DMSO mixtures
We have investigated the solvation shell dynamics of Na and Cl ion pairs in water DMSO mixtures of three compositions with xDMSO (mole fraction of DMSO) = 0.21, 0.35 and 0.48. Dynamical ion pair trajectories in these compositions are studied to analyze the diffusional behaviour of the solvent molecules in the primary and secondary solvation shells as well as the bulk solvent. As expected, the d...
