Low-temperature NMR spectroscopy of benzene on alumina and alumina-supported platinum reveals complex behavior. Physisorbed benzene on alumina shows multisite behavior. The chemisorbed benzene on the supported catalyst shows, in the dipole-dipoledecoupled proton spectrum, evidence of platinum-proton ...

The proton chemical shifts have been obtained from the NMR spectra of nine γ‐substituted pyridines. The substituent‐induced chemical shifts, which were calculated by subtracting from each observed value the corresponding proton shift of the unsubstituted pyridine, were found to be comparable to the...
The proton NMR spectra of several diphenyl, dithienyl and difurylspiroketones have been analysed and compared with the spectra of the analogous spiroketones without aryl groups. The comparison reveals that the two benzene, thiophene and furan rings in the diarylspiroketones exert a strong shielding...

The results obtained are consistent with the ...
Analysis of A2B2 High-Resolution NMR Spectra. I. Furan, Thiophene, and Disubstituted Benzenes The features of certain classes ofA2B2spectra are investigated systematically relative to the parameters involved, and these characteristic spectra are giv... DM Grant,RC Hirst,HS Gutowsky - 《Journal of...
The NMR-structure of the A-ATPase subunit F revealed a two-domain structure and the flexible C-terminal domain binds to the C-terminal domain of VHA-B (Coskun et al., 2004; Gayen et al., 2007). The arrangement of peripheral stalks resembles a scaffold which anchors the V1-domain to...
