红外光谱(IR)和拉曼光谱（Raman）1引言1.1红外光谱的发展 红拉外曼光光谱谱（（InRfaramraend）Spectroscopy,简称IR）分子光谱 两者得到的信息可以互补。在十九世纪初就发现了红外线,到1892年有人利用岩盐棱镜和测热幅射计(电阻温度计)测定了20多种有机化合物的红外光谱。1905年科伯伦茨发表了128种有机和无机化合...
The 2D homospectral and heterospectral correlation spectra were calculated for concentration-dependent IR and Raman spectral variations of β-lactoglobulin. The detailed analysis of cross peaks in asynchronous maps facilitates the assignment of components of the amide III band to different secondary ...
IR and Raman spectra (organic substancesChemInform is a weekly Abstracting Service, delivering concise information at a glance that was extracted from about 100 leading journals. To access a ChemInform Abstract of an article which was published elsewhere, please select a "Full Text" option. The ...
It is worth knowing that ATR and transmission produce slightly different spectra due to the differences between the two techniques. These spectral differences arise due to the way different wavelengths of IR light interact with the sample when the light is only partially absorbed during ATR. However...

A visible image of bacterial cells. The orange box indicates the location of IR imaging. B: O-PTIR infrared picture at 1655 cm-1, 50 nm step size. Collection time: ~1 minute. C: Submicron IR and Raman spectra were acquired from the indicated location on a single bacterial cell. Spectr...
FT-Raman spectroscopyDFT and PED calculationsFT-IR and FT-Raman spectra of 4-chloro-2-(4-bromophenylcarbamoyl)phenyl acetate were recorded and analyzed. The vibrational wavenumbers and corresponding vibrational assignments were examined theoretically using the Gaussian03 set of quantum chemistry codes. ...
