Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In solids spinning at the magic angle, the indirect detection of single-quantum (SQ) and double-quantum (DQ) N-14 spectra (l = 1) via spy nuclei S = 1/2 such as protons can be achieved in the manner of heteronuclear single- or multiple-quantum correlation ...
The MCM-41 supported hydrides [( SiO)(2)TaH], 1a, and [( SiO)(2)TaH3], 1b, cleave N-H bonds of ammonia at room temperature to yield the well-defined imido amido surface complexes [( SiO)(2)Ta-(NH)(NH2)], 2, and 2 center dot NH3. Additionally, the surface s ...
The detn. of residual dipolar couplings (RDCs) by quant. J spectroscopy methods such as heteronuclear single quantum correlation with phase encoded coupling (HSQC-PEC) is prone to systematic errors that may be caused by differential attenuation during the ...
In this study, LIDAR snow depths, bare ground elevations (topography), and elevations filtered to the top of vegetation (topography + vegetation) in five 1-km2 areas are used to determine whether the spatial distribution of snow depth exhibits scale invari ...

The synthesis and structural properties of three new hydridorhodium(III) complexes are reported. Hydrogenolysis of the cyclometalated Rh dichloride complexes [RhCl2{(S,S)-benbox(Me2)}] (2a-c; benbox(Me2) = 3,5-dimethyl-2,6-bis[(4-R1-4-R2-4,5-dihydrooxazol- ...
We present the design, fabrication and test of high-Q factor radiofrequency planar microcoils for nuclear magnetic resonance (NMR) spectroscopy in small volume samples. The coils are fabricated on glass wafers using high-aspect ratio SU-8 photoepoxy and co ...
Ru(II)-η6-p-cymene compds. bearing pyrone-derived ligands, which were obtained by Mannich reactions between kojic acid and piperidine or morpholine analogs, have been synthesized. The compds. were characterized by NMR spectroscopy, mass spectrometry, therm ...
To detect bronchial carcinoma by autofluorescence, we measured the spectra of tumor and normal tissue in situ, in an in vivo model and in vitro by fiber optic spectrometer and two-dimensional resolved microspectroscopy. The in situ measurements were perfor ...
We record double resonance spectra of the 4nu(1) band of jet-cooled C-13-methanol using single rotational state selection in the nu(1) fundamental and subsequent promotion of the selected molecules to the fourth vibrational level. We then detect transition ...
