NIR-FT-Raman spectroscopy was applied for a nondestructive analysis of single seeds (fruit mericarps) of 36 accessions belonging to various species of the Apiaceae family. Main seed components such as fatty acids, polysaccharides, proteins, and lignin were identified based on the obtained Raman spectra. Variation at the species and genus level was related to differences observed between spectra...

A novel technique for glucose sensing using collagen based thin film and zinc oxide (ZnO) nanoparticles, the Zinc Oxide Collagen Glucose Sensor (ZnOCGS) presented here. The Zinc oxide is synthesized using the two medium namely treating with 1.Ethanediol medium (Ethylene glycol) and 2.Water medium. It is characterized using the analytical techniques such as Fourier Transform infrared spectroscop...

PURPOSE To qualify the FT-Raman spectral data of primary and metastatic cutaneous melanoma in order to obtain a differential diagnosis. METHODS Ten normal human skin samples without any clinical or histopathological alterations, ten cutaneous melanoma fragments, and nine lymph node metastasis samples were used; 105, 140 and 126 spectra were obtained respectively. Each sample was divided into ...

The FTIR and FT Raman spectra of 2,3dibromofuran have been recorded in the region 4000-400 cm -1 and 4000-100 cm -1 respectively. The optimized geometry, frequency and intensity of vibrational bands of 2,3-dibromofuran were obtained by Density Functional Theory (DFT) using 6-311++G(d,p) basis set. The harmonic vibrational frequencies were calculated and scaled values have been compared with exp...

Nano sized ZnS and MnS2 were synthesized through a simple wet chemical route. In this Synthesis metal sulfides were used as the starting material and allowed to react with the transition metal source at 60°C for 75 minutes. The products were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Photoluminescence spectra (PL), Raman Spectra, Thermogravimetry analysis Diff...

-The vibrational modes of clay minerals are uniquely accessible to FT Raman spectroscopy, but this potentially powerful technique has found limited application to the study of clay mineral structure. Raman spectra in the 50 to 3800 cm-t region were obtained for a number of kandite clays. The kandite clay minerals are characterised by relatively intense bands centred at 142.7 cm -I for kaolinite...

FT-Raman Spectroscopy was applied to identify biochemical alterations existing between inflammatory fibrous hyperplasia (IFH) and normal tissues of buccal mucosa. One important implication of this study is related to the cancer lesion border. In fact, the cancerous – normal border line is characterized by the presence of inflammation and its correct discrimination would increase the accuracy in...

The FT-Raman and FT-infrared spectra of (1-methyluracilato)silver, [Ag(C(5)H(5)N(2)O(2))] in the solid state have been studied. The complex is a polymer in which one silver ion is linearly bonded to two 1-MeU ligands through the deprotonated N(3) sites and another silver ion is tetrahedrally coordinated to the four 1-MeU ligands through the O2 and O4 carbonyl oxygen atoms. The harmonic vibratio...

Electrochemical reduction of solution cast and self-assembled graphene oxide (GO) films on Au surfaces were studied using organic solvents. During the cyclic voltammetry measurements the structural changes in the films were recorded focusing on in situ infrared and Raman techniques. Both FT-Raman and dispersive Raman spectroscopy were utilized for the reduction studies. The spectroelectrochemic...

The molecular structure, vibrational frequencies, infrared intensities and Raman scattering activities of carboplatin were calculated by the modified mPW1PW91 (mPW) density functional model using several basis sets. The results from natural bond orbital (NBO) analysis have provided new insights into platinum–ligand bonding, the hybridization of atoms and the electronic structure of the title mo...
