The FTIR spectrum of the surface complex formed under wet conditions exhibited vibrational bands that could not be assigned to those of the parent benzene molecule or to those of previously observed chemisorbed Type I or Type II complexes. ~3C MAS NMR spectra of ~3C-enriched benzene sorbed onto...
using adsorption data at relative pressure (P/P0 ) of 0.05–0.25, and The FT-IR spectrum of modified silica aerogel CSA-0 and the total pore volume was estimated from the amount adsorbed at a carbon–silica aerogel composite CSA-2 is shown in Fig. 2. The FT-IR relative pressure of...
IR spectra of the surface species formed on Fe-Y and Fe- mordenite showed the bands in the range of1300 – 1400 cm–1 and 1500 – 1600 cm–1. These bands appeared in the IR spectrum starting from 300°C and they were very stable. Evacuation at 300°C even resulted in an increase ...
The catalytic decomposition of ethanol is a good example, where using different oxide supports, the end products vary in a large spectrum from hydrogen to different oxygenated compounds [40]. When hexagonal boron nitride (h-BN) was selected as a support for gold in ethanol decomposition, acetal...
The formation of polyimides was confirmed by means of elemental analysis, IR and NMR spectrosco- py. The typical IR spectrum of Vb is shown earlier in Figure 1. All polyimides exhibited characteristic imide group absorptions around 1781 and 1731 cmÀ1 (typical of imide carbonyl asymmetrical ...

The two short agostic Si—H–Mg interactions (Mg—H = 2.2, 2.5 Å) are represented by two low ν(Si—H) frequencies in the IR spectrum (2,040, 1,880 cm−1).233 The bonding between Li and Sn and Pb has been investigated computationally with SCF/HF (Self-Consistent Field/Hartree...
the combustion synthesis was accomplished in a domestic microwave oven within 3 min. Fig. 1 illustrates the physical, chemical properties and formation mechanism of CUA. As shown in Fig. 1a, three peaks are observed for the CUA in27Al MAS NMR spectrum. The two characteristic peaks with chemica...
