The Principles of Nonlinear Optics
TL;DR: In this article, the authors present a general description of wave propagation in nonlinear media, including high-resolution nonlinear optical spectroscopy, and four-wave mixing and mixing.
Journal ArticleDOI
Surface properties probed by second-harmonic and sum-frequency generation
TL;DR: In this article, the authors used second-harmonic generation and the related technique of infrared-visible light sum-frequency generation to monitor surface dynamics and reactions with sub-picosecond time resolution.
Journal ArticleDOI
Sum-Frequency Vibrational Spectroscopy on Water Interfaces: Polar Orientation of Water Molecules at Interfaces
Journal ArticleDOI
Vibrational spectroscopy of water at the vapor/water interface.

TL;DR: Using infrared-visible sum-frequency generation, the OH stretch vibrational spectra of water at the vapor/water interface are obtained and it is deduced that more than 20% of the surface water molecules have one free OH projecting into the vapor.
Journal ArticleDOI
Mapping molecular orientation and conformation at interfaces by surface nonlinear optics
Xiaowei Zhuang,Xiaowei Zhuang,Paulo B. Miranda,Paulo B. Miranda,Doseok Kim,Doseok Kim,Y. R. Shen,Y. R. Shen +7 more
TL;DR: Second-order nonlinear optics can be used to quantitatively determine the orientation of chemical bonds or submoieties of a fairly complicated molecule at an interface, and therefore completely map out its orientation and conformation as mentioned in this paper.
