As such, the infrared spectrum can be used as a ?ngerprintfor identi?cationby the comparison of the spectrum from an ‘‘unknown’’with previously recorded reference spectra. This is the basis of computer-based spectral searching. In the absence of a suitable reference database, it is ...
In the IR spectra only subtle changes in comparison to the spectrum after activation of Pt/SZ were observed. In the active state of Pt/SZ neither the OH groups nor the sulfates are involved as adsorption sites for n -hexane. Therefore, Pt-proton adducts near sulfate groups and hydride ions...

The UV-Vis spectrum and 1 H and 13 C NMR chemical shifts of the molecule were studied. Furthermore, Thermodynamic properties, NLO and MESP were likewise assessed and interpreted. Comparison of simulated spectra with the experimental spectra gives significant information about the ability of the ...

Its molecular formula was established as C13H21NO7S (m/z [M-H]À 334.0960, +0.2 mmu) by high-resolution electrospray ionization-mass spectrum. The structure of 1 was mainly elucidated by the analyses of NMR spectra, including heteronuclear single-quantum coherence, double- quantum-filtered ...
The IR and UV spectra of 2 were similar to those of 1. Most of the NMR spectroscopic data for 2 were also similar to those of 1 (Table 1). In the 1H NMR spectrum of 2, the singlet signal due to the oxymethylene group at H2-10 in 1 was replaced with a singlet methyl proton (...
In most cases, the compounds show broad-spectrum (Gram + & Gram bacteria) activities that are comparatively, slightly less active or equipotent to the antibiotic and antifungal agents in the comparison tests. 展开 关键词: Antimicrobial Bidentate Chelating Disk diffusion Gentamycin Raman ...
Currently we can only speculate on the mechanism of C-Cl bond formation, due to the complex 1H-NMR spectrum of the chlorination reaction mixture. The η2-bound carboxylate ligand in complex 2 Molecules 2015, 20 10125 may open to η1-bound to give an open coordination site for oxidative ...
