	abstract = "A novel SiO<SUB>2</SUB>-deposited CaF<SUB>2</SUB> (SiO<SUB>2</SUB>/CaF<SUB>2</SUB>) substrate for measuring vibrational sum-frequency generation (SFG) spectra of silane-based chemisorbed monolayers in aqueous media has been developed. The substrate is suitable for silanization and transparent over a broad range of the infrared (IR) probe. The present work demonstrates the practical application of the SiO<SUB>2</SUB>/CaF<SUB>2</SUB> substrate and, to our knowledge, the first SFG spectrum at the solid/water interface of a silanized monolayer observed over the IR fingerprint region (1780-1400 cm<SUP>&#8722;1</SUP>) using a back-side probing geometry. This new substrate can be very useful for SFG studies of various chemisorbed organic molecules, particularly biological compounds, in aqueous environments.",
