“…They all agree quantitatively with the 'standard' intensity spectra measured by Wei et al first published in 2001 [148,186]. Based on previous SHG phase measurement results [148,187], which discovered that the absolute phases of various nonresonant liquid surfaces are consistent with the phase of the air/water interface, while there was significant phase shift (about 25°) from that of the air/water interface and that of the z-cut quartz crystal surface, which have been used as the standard phase reference in SHG and SFG-VS phase measurement [91,114,176,[188][189][190][191]. Such inconsistency between all the non-resonant liquid surfaces and the quartz crystal surface was attributed to the different degrees of interferences between the SFG-VS signal generated from the non-resonant liquid surfaces with the quartz crystal phase reference, and the interference between the SFG-VS signal generated from the quartz crystal standard with the same quartz crystal phase reference.…”

Sum-frequency generation vibrational spectroscopy (SFG-VS) was first developed in the 1980s and it has been proven a uniquely sensitive and surface/interface selective spectroscopic probe for characterization of the structure, conformation and dynamics of molecular surfaces and interfaces. In recent years, there have been many progresses in the development of methodology and instrumentation in the SFG-VS toolbox that has significantly broadened the application to complex molecular surfaces and interfaces. In this review, after presenting a unified view on the theory and methodology focusing on the SFG-VS spectral lineshape, as well as the new opportunities in SFG-VS applications with such developments, some of the controversial issues that have been puzzling the community are discussed. The aim of this review is to present to the researchers and students interested in molecular surfaces and interfacial sciences up-to-date perspectives complementary to the existing textbooks and reviews on SFG-VS.

Single-channel heterodyne-detected sum frequency generation (HD-SFG) spectroscopy for selectively measuring vibrational spectra of liquid interfaces is presented. This new methodology is based on optical interference between sum frequency signal light from a sample interface and phase-controlled local oscillator light. In single-channel HD-SFG, interferometric and spectrometric measurements are simultaneously carried out with an input IR laser scanned in a certain wavenumber range, which results in a less task than existing phase-sensitive sum frequency spectroscopy. The real and imaginary parts of second-order nonlinear optical susceptibility (χ((2))) of interfaces are separately obtained with spectral resolution as high as 4 cm(-1) that is approximately six times better than existing multiplex HD-SFG. In this paper, the experimental procedure and theoretical background of single-channel HD-SFG are explicated, and its application to the water/vapor interface is demonstrated, putting emphasis on the importance of a standard for the complex phase of χ((2)).
