2D-FTIR Spectroscopy of bacterioRhodopsin
AIP Conference Proceedings, 20002D-FTIR Spectroscopy was applied to study the slower states of the membrane protein bacterioRhodopsin (bR) photocycle, with the bR adsorbed on a ZnSe ATR-crystal. 2D-FTIR absorbance changes are presented in a more convenient way for analysis than in traditional 2D-FTIR spectroscopy.

FTIR spectroscopy and DFT studies of carbosilane dendrimers
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2008The FTIR spectra of G(3), G(4), and G(9) generations of polybutylcarbosilane dendrimers have been recorded and analyzed. The structural optimization and normal mode analysis were performed for G(1) generation on the basis of density functional theory (DFT).

FTIR Emission spectroscopy of surfaces
Journal of Molecular Structure, 1982Abstract A number of vibrational spectroscopic techniques are available For the study of surfaces, such as ATR, IR reflection-absorption, IR emission, etc. Infrared emission is hardly used, although interesting applications are possible now due to the high sensitivity of Fourier transform IR (FTIR) spectrometers. Two examples, where infrared emission

Collagen types analysis and differentiation by FTIR spectroscopy
Analytical and Bioanalytical Chemistry, 2009Abnormal formation and organization of collagen network is commonly observed in many organ pathologies, but analytical techniques able to reveal the collagen biodistribution are still lacking. In this study, Fourier-transform infrared (FTIR) spectroscopy has been used to analyze type I, III, IV, V, and VI collagens, the most important compounds of ...

Industrial applications of FTIR spectroscopy
SPIE Proceedings, 1994The position and advantages of FT-IR among other analytical techniques are discussed, especially in the surface and microanalyses. Two typical examples of FT-IR applications being done recently in our laboratories are presented. Molecular orientation and surface morphology of mechanically rubbed polyimide films used for the alignment layer of liquid ...

Biomedical FTIR Spectroscopy of Lipids
2009This essay shows how Fourier Transform infrared spectroscopy (FTIR) can be applied to study membrane phase behavior of cells that are relevant for biomedical applications such as red blood cells and platelets. FTIR studies are minimally invasive and do not require labeling.

HT-FTIR spectroscopy of riebeckite
2015Changes in physical properties of Fe-amphiboles at increasing T have been proven to be crucial in modeling the electrical conductivity of subducted rocks in convergent margins (Reynard et. al., 2011). Oxidation of Fe2+ to Fe3+ within the octahedral sites, which in turn is aimed at achieving local electroneutrality during deprotonation occurring at high

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 ...
