Thin films of water between glass plates were investigated in this study with regard to water structure and dynamics in the temperature range of 278313 K. We further;:. investigated how addition of 1-butanol.(0.05 and 0.5 M) affects the range and properties of the surface induced Water. structures. From the observation of two H-1. nuclear Magnetic resonance (NMR) water resonances and two relaxation components, it was found that the interfacial water exists in a two state mixture in dynamic equilibrium, with the respective structures interpreted as being high density water (HDW) and low density water (LDW). In the absence of 1-butanol, the LDW state is more pronounced, with a further shift in equilibrium toward the LDW state with an increase in temperature. However, in water film samples containing 1-butanol, the HDW state dominates at low temperatures while the LDW state becomes more visible at higher temperatures. Furthermore, the addition of 1-butanol significantly increased the extent of the surface-induced water structures. NMR relaxation shows that the dynamics of water in the HDW state is significantly affected by the presence of 1-butanol and further indicates that the distribution of values for the enthalpy of activation associated with translational motion of water molecules in the HDW state is narrower in the 0.05 M 1-butanol sample than in the 0.5 M 1-butanol sample.
