2001, Volume 105B Xiaoming Shang, Alexander V. Benderskii, and Kenneth B. Eisenthal*: Ultrafast Solvation Dynamics at Silica/Liquid Interfaces Probed by Time-Resolved Second Harmonic Generation. Page 11578. There is a misprint in this article based on an incorrect selection of the S1 r S0 transition dipole direction of IR144, which was pointed out to us by Prof. D. Jonas. The next to last paragraph of the Experimental Section should be replaced by the following: Molecular orientation of IR144 with respect to the interface normal was obtained using the null angle technique40 modified to take into account the Fresnel factors for the TIR geometry41 used in our experiment. With the assumption that the nonlinear response of IR144 can be characterized by a single molecular hyperpolarizability element Rξξξ dominated by the S1 r S0 transition whose dipole is parallel to the longest axis of IR144,42 the transition dipole approaches parallel to the surface at both studied interfaces. This would indicate that the longest axis of IR144 molecules lies nearly “flat” on the surface. 10.1021jp0135196 Published on Web 11/02/2001
