The quantitative importance (several ppm) of the effect of solute–solvent van der Waals' interactions on the13C chemical shift is shown for a non polar solute,n-pentane, in solution in 17 solvents and in the gas phase. The van der Waals screening constant term is discussed in respect to...
The broad resonance signal observed at low temperature (7 K) withg = 3.5 appears as characteristic of the trivalent state in UZrF7(powder), U(C5H5)3•tétrahydrofuran, and U(C5H5)3•CH3−(frozen solutions).E. J. SouliéG. FolcherH. Marquet-Elliscanadian journal of chemistry...

Synthesis of all monodeuterio indazole derivatives has allowed the assignment of the seven carbons in the13C nmr spectrum of indazole. Some1J,2J, and3Jcoupling constants have been measured from the coupled spectrum.JoséElgueroAlain Fruchier...
The NMR spectra of monochloro-, monobromo- and monofluoroacetone (CH 3 CO CH 2 X with X = Cl, Br, F) oriented in a nematic phase have been measured and the direct dipolar coupling constants determined. The barrier to internal rotation for the CH 2 F group has been studied for ...
14 N-NMR. measurements using the Fourier Transform technique are presented and compared to C. W. experiments. The F. T. technique is especially advantageous for relaxation time measurements. However, since 14 N-nuclei may have widely different relaxation times, it is often not possible to have...
