Zeitaufgelöste FTIR‐Differenzspektroskopie

Nachrichten aus Chemie, Technik und Laboratorium, 1993
AbstractMit der Fourier‐Transform‐Infrarot (FTIR)‐Differenzspektroskopie lassen sich nicht nur Chromophorreaktionen von Proteinen, sondern darüber hinaus auch Reaktionen der Proteinseitengruppen und des Proteingerüsts molekular‐ und zeitaufgelöst erfassen.

FTIR Spectroscopy of Metalloproteins

2014
Absorption of infrared radiation by proteins gives important information about their structure and function. The most intense infrared bands correspond to the overlap of all the peptide bond absorption. Additionally, in many metalloproteins their prosthetic groups have intrinsic ligands or bind substrates/inhibitors that absorb intensively in the ...

Fourier transform infrared (FTIR) spectroscopy

Photosynthesis Research, 2009
Fourier transform infrared (FTIR) spectroscopy probes the vibrational properties of amino acids and cofactors, which are sensitive to minute structural changes. The lack of specificity of this technique, on the one hand, permits us to probe directly the vibrational properties of almost all the cofactors, amino acid side chains, and of water molecules ...

FTIR Spectral Components of Schwertmannite

Environmental Science & Technology, 2010
Fourier transform infrared (FTIR) spectral components of three dominant groups of sulfate species in synthetic schwertmannite (Fe(8)O(8)(OH)(6-x)(SO(4))(x)*nH(2)O) are presented. These components were extracted by multivariate curve resolution analysis of spectra obtained from N(2)(g)-dry samples initially reacted in aqueous solutions (pH 3-9) at room ...

Profiling cocaine by ATR–FTIR

Forensic Science International, 2015
In this article, five hundred and thirteen cocaine seizures of the State of Rio Grande do Sul (Brazil) were analyzed by Fourier transform infrared spectroscopy (FT-IR) in the fingerprint region (1800-650 cm(-1)) to profiling and evaluate the pharmaceutical products used as adulterants.

FTIR And TGA/FTIR Characterization Of A Polyethylene Photodegradable Concentrate

SPIE Proceedings, 1989
An integrated thermogravimetric/Fourier transform infrared (TGA/FTIR) system is used to detect the presence of a fatty acid in a commercial, photodegradable, polyethylene concentrate. This technique is simple, rapid, convenient, and requires minimal sample manipulation. It can be very useful for monitoring the differences in resin concentrates. Results

FTIR spectroscopy and FTIR microscopy of vacuum-evaporated polyimide thin films

Vibrational Spectroscopy, 1999
Abstract Polyimide (PI) thin films can be formed by vapor co-deposition of the precursor molecules pyromellitic dianhydride (PMDA) and 4,4′-oxydianiline (ODA) if the resulting polyamic acid film is heated above 150°C. The effects of dose stoichiometry and curing temperature on the imidization rate and crystallization of PI films were investigated ...
