IR and 13C NMR spectroscopyAdsorption and decomposition of chlorofluorocarbons, with (CHClF 2) and without (CCl 2F 2) hydrogen content were investigated on zeolites NaY and HZSM-5. The IR and 13C NMR spectroscopic results are in good agreement and proved that the intermediates of the surface ...
Physicochemical properties of bis(diisopropylammonium) dihydrogendiphosphate trihydrate, (C6H16N)2H2P2O7·3H2O are discussed on the basis of X-ray crystal structure investigation. It crystallizes in the monoclinic system with P21/n space group. Its unit cell dimensions are a = 12.152(1) ...
The structural consequences of template removal by calcination, and (under non-caring conditions) those caused by overheating have been studied by X-ray diffraction, ja:math MAS-NMR, FT-IR and XPS spectroscopies using Fe-ZSM-5 (Si/Fe=15.0) and Ti-ZSM-5 (Si/Ti=29.8) samples. The heat-...
Note that approaches widely used in petrochemical methods of analysis, such as elemental (X-ray fluorescence, absorption and emission optical spectroscopy), fragment and component (IR spectroscopy, mass spectrometry, chromatography) analyses are indirect (unlike NMR) because they require using reference ...
As early as 1999, Attaelmannan et al. used proton nuclear magnetic resonance spectroscopy (NMR) to determine the main VFAs in rumen fluid15. Concentrations of acetate, propionate and butyrate in the rumen measured by NMR were not significantly different from the values determined by gas chromatogr...
