FT-IR spectrometry in materialography
Materials Characterization, 1995Abstract Fourier transform infrared (FT-IR) spectroscopy was utilized in the analysis of various materials as a complementary technique to scanning electron microscopy during microstructural characterization. Applications included: (1) the identification of resin and filler additives in organometallic cements; (2) differentiation between resin type ...

IR spectroscopy is one of the absorption spectroscopies. As found in a UV-vis spectrometer, IR spectrometers were also developed on the same concept of a UV-vis spectrometer involving a dispersive optical element represented by a prism or a diffraction grating.

Perhaps the most widely accepted model of ionomer superstructure is the multiplet-cluster concept advanced by Eisenberg [1,2]. This framework has dominated the interpretation of many vibrational spectroscopic studies to the extent that specific infrared bands and Raman lines have been separately assigned to multiplets or clusters.

FT-IR Matrix Isolation Studies
1980Matrix isolation is a technique for trapping isolated molecules of the species to be studied in a large excess of an inert material by rapid condensation at a low temperature, so that the diluent forms a rigid cage or matrix. At a sufficiently low temperature, diffusion of the solute species is prevented and thus reactive species may be stabilized for ...

Fehleranalyse mit FT‐IR‐Mikroskopie
Nachrichten aus der Chemie, 2008AbstractZur Analyse von Fehlstellen, deren Ausdehnung im Produkt wenige Millimeter oder Mikrometer beträgt, dienen mikroskopische Techniken. Die Fourier‐Transform‐ Infrarot‐(FT‐IR‐)Spektroskopie bestimmt die chemische Beschaffenheit von Fehlstellen mit hoher Ortsauflösung.

Applied Spectroscopy, 1982
Two approaches to phase correction in FT-IR spectroscopy are discussed. Using synthetic data, both the Mertz method and the symmetrization-convolution method are evaluated with respect to the accurate reproduction of a single-beam spectrum. The variation in photometric accuracy with (1) the number of points used in the phase calculation, and (2 ...

Određivane formaldehida FT-IR spektrometrijom
1998Aldehidi su reaktivni organski spojevi koji zagađuju životni okoliš, a mogu se pojaviti i u namirnicama i to najčešće kao formaldehid. Pri kvantitativnom određivanju formaldehida u namirnicama, važna je mogućnost koncentriranja formaldehida u nekom adsorpcijskom sustavu u kojem određena komponenta sustava odmah reagira s formaldehidom. Takvi sustavi su
