Comment on "Orientational Distribution of Free O-H Groups of Interfacial Water is Exponential"
Wei Gan, Ran-ran Feng, Hong-Fei Wang
In a recent letter (PRL,121,246101,2018), Sun et al. reported that combined MD simulation and sum frequency generation vibrational spectroscopy (SFG-VS) measurements led to conclus…
Beyond the Gouy-Chapman Model with Heterodyne-Detected Second Harmonic Generation
Paul E. Ohno, HanByul Chang, Austin P. Spencer +4
We report ionic strength-dependent phase shifts in second harmonic generation (SHG) signals from charged interfaces that verify a recent model in which dispersion between the funda…
On Second-Order Vibrational Lineshapes of the Air/Water Interface
Paul Ohno, Hong-fei Wang, James Skinner +2
We explore by means of modeling how absorptive-dispersive mixing between the second- and third-order terms modify the imaginary chi(2)total responses from air/water interfaces unde…
Second-Order Spectral Lineshapes from Charged Interfaces
Paul E. Ohno, Hong-fei Wang, Franz M. Geiger
Second-order nonlinear spectroscopy has proven to be a powerful tool in elucidating key chemical and structural characteristics at a variety of interfaces. However, the presence of…
Phase-referenced Nonlinear Spectroscopy of the alpha-Quartz/Water Interface
Paul E. Ohno, Sarah A. Saslow, Hong-fei Wang +2
Probing the polarization of water molecules at charged interfaces by second harmonic generation spectroscopy has been heretofore limited to isotropic materials. Here, we report non…
Spectroscopic Evidence for the Specific Na+ and K+ Interactions with the Hydrogen-bonded Water Molecules at the Electrolyte Aqueous Solution Surfaces
Ran-ran Feng, Hong-tao Bian, Yuan Guo +1
Sum frequency generation vibrational spectra of the water molecules at the NaF and KF aqueous solution surfaces showed significantly different spectral features and different conce…
