FTIR and Raman Spectroscopy of Rhodopsins

2022
Vibrational spectroscopy such as FTIR and Raman spectroscopy is a powerful, sensitive, and informative method for studying protein structural changes in rhodopsins during their functions. The usefulness has been historically proven for the study of bacteriorhodopsin and bovine rhodopsin before their structural determination of rhodopsins.

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 spectroscopy of adsorbed ozone

Chemical Physics Letters, 2020
Abstract FTIR spectra of ozone adsorbed at 77 K on a number of oxide adsorbents were investigated. Special attention was paid to the position and isotopic splitting of the band of ν1+3 combination vibration. For titania eight distinct bands were distinguished and put in correspondence with the bands of ν1 and ν3 vibrations.

FTIR Spectroscopy for Carbon Family Study

Critical Reviews in Analytical Chemistry, 2016
Fourier transform Infrared (FTIR) spectroscopy is a versatile technique for the characterization of materials belonging to the carbon family. Based on the interaction of the IR radiation with matter this technique may be used for the identification and characterization of chemical structures. Most important features of this method are: non-destructive,

Raman and FTIR spectroscopies of fluorescein in solutions

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2001
Raman and Fourier transform-infra red (FT-IR) spectroscopies of fluorescein in aqueous solutions have been investigated in the pH range from 9.1 to 5.4. At pH 9.1 fluorescein is in the dianion form. At pH 5.4, fluorescein is a mixture of monoanion (approximately 85%), dianion and neutral forms (together approximately 15%).

FTIR Spectroscopy of Flavin-Binding Photoreceptors

2014
Light-induced difference Fourier transform infrared (FTIR) spectroscopy is a powerful, sensitive, and informative method to study structure-function relationships in photoreceptive proteins. Strong absorption of water in the IR region is always problematic in this method, but if water content in the sample is controlled during measurements, this method

FTIR spectroscopy applied to woodflour

Composite Interfaces, 1996
The features of infrared spectra of woodflour obtained by transmission and diffuse reflectance (DRIFT) are discussed. Intrinsic differences between the two techniques, as well as differences in sample preparation for transmission (pressed pellet) or DRIFT (simple mixing with powered KBr), affect the appearance of the spectra recorded.
