Total internal reflection Raman spectroscopy.

Near IR scanning angle total internal reflection Raman spectroscopy at smooth gold films.

Total internal reflection (TIR) Raman and reflectivity spectra were collected for nonresonant analytes as a function of incident angle at sapphire or sapphire/smooth 50 nm gold interfaces using 785 nm excitation. For both interfaces, the Raman signal as a function of incident angle is well-modeled by the calculated interfacial mean square electric field (MSEF) relative to the incident field tim...

Investigation of the structure of water at hydrophobic and hydrophilic interfaces by angle-resolved TIR Raman spectroscopy.

To analyse the surface- or interface-specific molecular structure of a condensed molecular system, it is important to measure the spectra of molecules near the surface. Total internal reflection (TIR) Raman spectroscopy is a sensitive technique for surface or interfacial analysis because it retrieves spectra in the region within ca. 100 nm of a surface. However, since the width of the interface...

Multiple spatially resolved reflection spectroscopy for in vivo determination of carotenoids in human skin and blood

Non-invasive measurement of carotenoid antioxidants in human skin is one of the important tasks to investigate the skin physiology in vivo. Resonance Raman spectroscopy and reflection spectroscopy are the most frequently used non-invasive techniques in dermatology and skin physiology. In the present study, an improved method based on multiple spatially resolved reflection spectroscopy (MSRRS) w...

Construction of a Total Internal Reflection Fluorescence Microscope to Study Lipid Domain Composition via Raman Spectral Imaging

Combined Raman and FT-IR spectroscopy Using the IlluminatIR module for Renishaw's inVia Raman microscopes

The IlluminatIR™ is commonly used with either a diamond contact ATR (attenuated total reflection) or a diffuse reflectance objective. The sample can be viewed, and Raman spectra collected, either through these objectives or through the high quality microscope objectives supplied with the inVia Raman microscope. Simple switching between video view, IR acquisition, and Raman acquisition allows IR...
