Fraction of the signal due to interfacial water. Solid lines are fractions from fitting the infrared spectrum to a two component model consisting of bulk water as the core spectrum and w0 = 2 as the interfacial spectrum. The points are the interfacial weight a extracted by simultaneously fitting the vibrational population relaxation and anisotropy decays in the interfacial region to a two component model. The agreement between the interfacial fractions determined by these two methods indicates that the transition dipole moment of interfacial water and bulk water at a particular frequency is quite similar. Blue line and circles - w0 = 25. Black line and triangles - w0 = 37. Red line and squares - w0 = 46.
