摘要：

The structure of water in water/AOT/n-heptane reverse micelles has been studied as a function of the [H2O]/[AOT] ratio (W) by using the absorption IR due to O-H stretching modes in the 3800-3000 cm(-1) range. The results show that the IR spectra can be expressed as a sum of contributions from bound- and bulk-like water. The fraction of water in the two regions within the water pool was evaluated as a function of W. The ''bound'' water region seems to hold 3.5 water molecules (corresponding to 7 O-H oscillators) per AOT molecule and its formation is nearly complete at W > 6.
