Raman resonance (RR) is a vibrational spectroscopy, which reports transitions between different vibrational energy levels in a molecule (Que, 2000; From: Methods in Enzymology, 2017 About this pageAdd to MendeleySet alert On this page Definition Chapters and Articles Related Terms Recommended Publicati...
A detailed procedure for the quantitative analysis of aromatic and aliphatic hydrogen based on infrared spectroscopy was set up and implemented on some carbon-based materials produced from organic precursors (naphthalene pitch) and/or relevant in combustion field (asphaltenes, carbon particulate matter, ...
Infrared spectroscopy is a technique based on the absorption or reflection of infrared radiation by chemical substances; each chemical substance having unique absorption spectra. Fourier Transform Infrared (FTIR) spectroscopy is used to identify biochemical compounds and examine the biochemical composition of...
Near-infrared (NIR) spectroscopy (e.g., LipiScan Coronary Imaging System) is a catheter-based technique that is currently under investigation for detecting coronary vulnerable plaques (Lau et al, 2004). It identifies the chemical composition of substances based on the differential absorption of ...
IR (infrared) andNIR (near-infrared) spectroscopymake use of different spectral ranges of light. Light in the NIR range possesses higher energy levels than IR light (Figure 1), and this impacts its interaction with a sample’s molecules. ...
Near-infrared (NIR) spectroscopy is a branch of vibrational spectroscopy that shares many of the principles that apply to other spectroscopic measurements. The NIR spectral region comprises two subranges associated with detectors used in the initial development of NIR instrumentation. The short-wavelength...
(i.e. its photon density) is up to twice as high as those generated by conventional synchrotrons, which have hitherto served as radiation sources for comparable approaches to molecular spectroscopy. In addition, the infrared radiation is both spatially and temporally coherent. All of these ...
Attenuated total reflectance infrared spectroscopy (ATR-FTIR) involves passing an incident ray of infrared light through a hemispherical crystal of a high refractive index material such as Ge, which reflects off the internal surfaces in contact with the functionalized sample. ...
