Intrinsic pH of water/vapor interface revealed by ion-induced water alignment
Kuo-Yang Chiang, Laetitia Dalstein, Yu-Chieh Wen
Protons at the water/vapor interface are relevant for atmospheric and environmental processes, yet to characterize their surface affinity on the quantitative level is still challen…
Direct Quantification of Water Surface Charge by Phase-Sensitive Second Harmonic Spectroscopy
Laetitia Dalstein, Kuo-Yang Chiang, Yu-Chieh Wen
We develop and verify a phase-sensitive second harmonic generation spectroscopic scheme that allows for direct determination of the absolute surface charge density and surface pote…
Nonlinear optical response of a gold surface in the visible range: A study by two-color sum-frequency generation spectroscopy. II. Model for metal nonlinear susceptibility
Bertrand Busson, Laetitia Dalstein
We present a modeling of the nonlinear optical response of a metal surface in order to account for recent experimental results from two-color Sum-Frequency Generation experiments o…
