We have studied the Fourier Transform Infrared (FT-IR) and the Fourier transform Raman (FT-Raman) spectra of stanozolol and oxandrolone, and we have performed quantum chemical calculations based on the density functional theory (DFT) with a B3LYP/6-31G (d, p) level of theory. The FT-IR and FT-Raman spectra were collected in a solid phase. The consistency between the calculated and experimental ...

stable homogeneous dispersions of carbon nanotubes (cnts) were prepared using ethanol as dispersing agent. then, using sol-gel method, dispersion in the hydroxyapatite matrix and its effects on the microstructure were investigated. the phase composition, chemical structure and morphological and size analyses were performed using xrd, ft-ir, sem, tem/saed/edx and raman spectroscopy. the influenc...

in this paper, the structure of a new 16-membered macrocyclic schiff base compound n,n′-(3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzylidene)propane-1,3-diamine, c22h26n2o4 (1), derived from 1,3-propanediamine and 3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzaldehyde has been studied by single crystal x-ray diffraction, dft calculations at b3lyp/6-31g** and ft-ir spectroscopy. the titl...

Interfacial oxidation and reduction of Prussian Blue (PB), KFe[Fe(CN)6]‚nH2O (n ≈ 10), powder were probed in situ with Fourier transform infrared attenuated total reflection (FT-IR/ATR) spectroscopy. The combination of electrochemistry in the absence of liquid electrolyte with internal reflectance FT-IR spectroscopy was accomplished using a simple two-electrode sandwich-type cell in which a cry...

In this work I present the study of the behaviour response of mouse broblasts NIH-3T3 under UVB radiation using Fourier transform infrared spectroscopy (FT-IR), the preferred method of infrared spectroscopy. FT-IR, in fact, it is convenient to study molecular cell processes because it has the potential to provide the identi cation of the vibrational modes of some of the major compounds (lipid, ...

Spatially resolved Fourier transform infrared (FT-IR) spectroscopy of single oral mucosa cells and FT-IR spectroscopy of liver cell fractions produced by sucrose density gradient centrifugation have been applied to acquire structural information of cell organelles. For the spatially resolved measurements, mapping as well as mercury cadmium telluride (MCT) focal plane array (FPA) detector techni...

OBJECTIVE This study was conducted to determine molecular structures related to carbohydrates and lipid in alfalfa hay cut at early bud, late bud and early flower and in the afternoon and next morning using Fourier transform infrared spectroscopy (FT/IR) and to determine their relationship with alfalfa hay nutrient profile and availability in ruminants. METHODS Chemical composition analysis, ...

Soft X-ray absorption spectroscopy coupled with nano-scale microscopy has been widely used in material science, environmental science, and physical sciences. In this work, the advantages of soft X-ray absorption spectromicroscopy for plant biopolymer research were demonstrated by determining the chemical sensitivity of the technique to identify common plant biopolymers and to map the distributi...
