FT-IR Spectroscopic Studies of Catalysts
The role of FTIR speetroscopy in catalytic studies is briefly discussed and some typical examples are shown. IR spectra of weakly bound hydrogen on PtjSi02 reveal surface heterogeneity; The hydrogen concentration on the surface is described by a Temkin isotherm. Adsorption of unsaturated C6 ring compounds on hydrogen poor PtjSi02 is essentially a self'-hydrogenation process resulting in the for...
متن کاملApplication of TG - DTA to study of Ancient Potteries from Kaveripakkam , Vellore district , Tamilnadu , India
Firing temperature Ancient Potteries are among the oldest and most significant technological innovations in the history of human achievement, and were the first truly synthetic material. Spectroscopic techniques are very useful tools to achieve a detailed knowledge of the art works. In the present study thermogravimetry (TG) and differential thermal analysis was carried out for pottery samples ...
متن کاملStructural Analysis of Hirudin Using FT-IR and FT-Raman Spectroscopic Techniques
FT-IR and FT-Raman spectra of hirudin have been recorded from the native solid hirudin. The conformation of the molecule has been discussed on the basis of IR and Raman data. It has been concluded that hirudin molecule has a mixed a-helix and random coil conformation.
متن کاملExperimental Spectroscopic (FT-IR, FT-Raman, NMR) and DFT Studies of 7-methoxy-4-bromomethylcoumarin
The vibrational fundamental modes of 7-methoxy4-bromomethylcoumarin (7BMC) have been analyzed by combining FTIR, FT-Raman and quantum chemical calculations. The structural parameters of the compound are determined from the optimized geometry by B3LYP method with 6-311++G (d, p) basis set. The harmonic vibrational frequencies were calculated and the scaled values have been compared with experime...
متن کاملFT-IR studies of zeolite materials: characterization and environmental applications
Synthetic zeolites are used widely throughout the petroleum refining and chemical process industries as selective adsorbents, catalysts and ion exchangers. The research described in this thesis focuses on the characterization and environmental applications of faujasite zeolites, including nanocrystalline Y zeolites that have particle sizes less than
