Solute rotation and solvation dynamics in an alcohol-functionalized room-temperature ionic liquid
Article Abstract:
An investigation of the steady-state and time-resolved fluorescence behaviors of two dipolar solutes, coumarin 153 and 4-aminophthalimide in an alcohol-functionalized room-temperature ionic liquid, 1-(hydroxyethyl)-3-methylimidazolium bis(trifluoromethanesulfonyl)imide is done to evaluate the polarity of the ionic liquid and to get detailed insight on the hydrogen bonding interaction between the ionic liquid and the probe molecules. A substantial slow down of the rotational motion of the one of the probe molecules is observed.

Solvation of Coumarin 314 at water/air interfaces containing anionic surfactants. I. Low coverage
Article Abstract:
The equilibrium and dynamical aspects of the solvation of Coumarin 314 adsorbed at water/air interfaces in the presence of sodium dodecyl sulfate surfactant molecules by using the molecular dynamics techniques are analyzed. An increase in the roughness and in the characteristic width of the water/air interface is seen due to the presence of the surfactant.

Molecular dynamics study of solvation of Coumarin-314 at the water/air interface
Article Abstract:
Molecular dynamics experiments are carried out to study equilibrium and dynamical aspects of orientations and solvation of Coumarin-314 lying at the aqueous/air interface. Stable interfacial solvation states for the probe are characterized by an orientation of its molecular plane mostly parallel mostly parallel to the interface.
