We use femtosecond two-colour mid-infrared spectroscopy to study the dynamics of aqueous solutions of salts in HDO:D2O. We find that the lifetime of the O–H stretch vibration of HDO molecules in the solvation shell of the halogenic anions Cl−, Br

We study the effects of ions on the structure and dynamics of the hydrogen bonds in liquid water. As a technique we use femtosecond two-color mid-infrared spectroscopy, since this technique allows a clear distinction of the dynamics of the first solv

The orientational-correlation time of water molecules in ionic solutions has been measured with femtosecond pump–probe spectroscopy. It is found that the addition of ions has no influence on the rotational dynamics of water molecules outside the fi

Femtosecond two-color mid-infrared pump−probe spectroscopy is used to study the vibrational relaxation and the hydrogen-bond dynamics of HDO dissolved in liquid H2O. By looking at the spectral dyna...

Aqueous solvation forms one of the most important but less understood topics of chemical physics. The main problem in the experimental study of aqueous solvation interactions is the distinction of the response of the solvating water molecules from th

The effects of ions on bulk properties of liquid water, such as viscosity, have suggested that ions alter water's hydrogen-bonding network. We measured the orientational correlation time of water molecules in Mg(ClO 4 ) 2 , NaClO 4 , and Na 2 SO 4 so

Using femtosecond mid-infrared pump-probe spectroscopy, we find that the vibrational energy relaxation, the orientational and hydrogen-bond dynamics of water molecules in the solvation shell of an ion are much slower than in neat liquid water.

We present a study of the orientational dynamics of aqueous solvation shells of halogenic anions in bulk water solution with femtosecond two-color midinfrared spectroscopy. These orientational dynamics have time constants between 2.5 and 12 ps, depen
