Journal ArticleDOI
Vibrational spectroscopy of the electrochemical interface by visible-infrared sum-frequency generation
TL;DR: In this article, the vibrational properties of electrochemical interfaces investigated by in situ infrared-visible sum frequency generation are presented and discussed, which represents a unique vibrational probe for buried interfaces.
Journal ArticleDOI
Potential-dependent structure of the interfacial water on the gold electrode
Satoshi Nihonyanagi,Shen Ye,Kohei Uosaki,Laurrent Dreesen,Christphe Humbert,Paul Thiry,André Peremans +6 more
TL;DR: In this article, a doubly tunable sum frequency generation (SFG) spectra demonstrate that the water molecules at gold/electrolyte interface change their orientation with applied potential.
Journal ArticleDOI
Influence of the metal electronic properties on the sum-frequency generation spectra of dodecanethiol self-assembled monolayers on Pt (111), Ag (111) and Au (111) single crystals
Laurent Dreesen,Christophe Humbert,M. Celebi,Jean-Jacques Lemaire,A. A. Mani,Paul Thiry,André Peremans +6 more
TL;DR: In this article, the authors performed infrared-visible sum-frequency generation (SFG) spectroscopy at different visible wavelengths between 450 and 650 nm in order to investigate the interaction between metallic substrates (Pt, Ag and Au) and 1-dodecanethiol self-assembled monolayers.
Journal ArticleDOI
Study of the water/poly(ethylene glycol) interface by IR-visible sum-frequency generation spectroscopy
Laurent Dreesen,Christophe Humbert,Philippe Hollander,A. A. Mani,K. Ataka,Paul Thiry,André Peremans +6 more
TL;DR: In this article, the vibrational properties of the water/poly(ethylene glycol) interface in the 2800-3800 cm−1 spectral range were investigated using infrared-visible sum-frequency generation spectroscopy.
Journal ArticleDOI
Electronic and molecular properties of an adsorbed protein monolayer probed by two-color sum-frequency generation spectroscopy
Laurent Dreesen,Christophe Humbert,Yannick Sartenaer,Yves Caudano,Cédric Volcke,Alaa Addin Mani,André Peremans,Paul Thiry,Sophie Hanique,Jean-Marie Frère +9 more
TL;DR: Two-color sum-frequency generation spectroscopy is used to probe the molecular and electronic properties of an adsorbed layer of the green fluorescent protein mutant 2 on a platinum (111) substrate and reveals two electronic transitions corresponding to the absorption and fluorescence energy levels which are related to two different GFPmut2 conformations: the B and I forms, respectively.
