Infrared absorption spectroscopy is a versatile analytical method that can identify different compounds in archaeological materials and sediments by measuring the portions of the infrared spectrum absorbed by specific molecules. This technique was developed in the 1930s for the characterization of industrial...

Because of the intense absorption of IR light by solvent (water), IR spectroscopy cannot be used as readily as Raman spectroscopy forin situmonitoring corrosion phenomenon in aqueous environments. Therefore, specific cells have to be designed with the aim of minimizing radiation losses by solvent ab...
Here, we investigated the oxidization process of three Co-PBAs by means of in situ infrared absorption (IR) spectroscopy. With use of an empirical rule of the frequencies of the CN− stretching mode in ferrocyanide ([FeII(CN)6]4−) and ferricyanide ([FeIII(CN)6]3−), the ...
The detailed electronic structure and coordination environment of Ir1/Ni LDH-T and Ir1/Ni LDH-V were further revealed by X-ray absorption near-edge spectroscopy (XANES) and extended X-ray absorption fine structure (EXAFS) studies. The normalized IrL3-edge XANES and EXAFS spectra of Ir1/Ni ...
The determination of protein-to-lipid ratio by infrared spectroscopy was first proposed by Navarro et al. [30]. Since proteins and lipids show distinctive absorption bands, the FTIR spectrum can be used to estimate the protein-to-lipid ratio by dividing the relative intensity of amide I protein...
