FTIR Spectrum of the ν4Band of DCOOD
Journal of Molecular Spectroscopy, 1999The FTIR spectrum of the nu4 band of deuterated formic acid (DCOOD) has been measured with a resolution of 0.004 cm-1 in the frequency range of 1120 to 1220 cm-1. A total of 1866 assigned transitions have been analyzed and fitted using a Watson's A-reduced Hamiltonian in the Ir representation to derive rovibrational constants for the upper state (v4 ...

Lignin Analysis by HPLC and FTIR
2017Fourier transform infrared spectroscopy (FTIR) is a simple non-destructive technique which allows the user to obtain quick and accurate information about the structure of the constituents of wood. High performance liquid chromatography (HPLC) is an analytical technique useful to determine the ratio of the lignin monomers obtained by the alkaline ...

FTIR and the illusion of superluminality
Frontiers in Optics 2004/Laser Science XXII/Diffractive Optics and Micro-Optics/Optical Fabrication and Testing, 2004The propagation of evanescent pulses under the conditions of frustrated internal reflection (FTIR) may appear as superluminal and non-causal, but only if it is treated as a 1D tunneling phenomenon. When its 3D nature is fully accounted for, it may be simply explained through a subluminal causal theory.

In this chapter, several analytical techniques to make the best use of the ‘ordinate scale’ of absorbance spectra are described. The techniques are on a concept of the multivariate analysis, which is usually called chemometrics. To employ chemometrics for spectral data analysis, the accuracy of the abscissa axis must be highly rigid.

2011 International Conference on Infrared, Millimeter, and Terahertz Waves, 2011
We apply mid-infrared near-field microscopy with broad-band spectroscopic operation to problems in biomineralization. Inspecting tooth material we find vibrational resonances of phosphate nanocrystals distinctly shifted from bulk phosphates. This is enabled by the extraordinary spectral narrowing promoted by the near-field interaction over far-field ...

Structural Characterization of Membrane Proteins and Peptides by FTIR and ATR-FTIR Spectroscopy
2012Fourier transform infrared (FTIR) spectroscopy is widely used in structural characterization of proteins or peptides. While the method does not have the capability of providing the precise, atomic-resolution molecular structure, it is exquisitely sensitive to conformational changes occurring in proteins upon functional transitions or upon ...

FTIR analysis of carbonate precursors in manganite coprecipitation synthesis by FTIR spectroscopy
2021The simple perovskite oxides, manganites, are nowadays subject of extensive research because of their electrical, magnetic and photocatalytic properties. Manganites described with general formula A1-xSrxMnO3 (A = Ca, Ba, La) were prepared by the coprecipitation method.

Infrared spectroscopy has proved to be a powerful tool for the study of biological molecules and the application of this technique to biological problems is continually expanding, particularly with the advent of increasingly sophisticated sampling techniques associated with Fourier transform infrared spectroscopy in recent decades.
