Journal ArticleDOI
A Rationale for the Large Breathing of the Porous Aluminum Terephthalate (MIL‐53) Upon Hydration
Thierry Loiseau,Christian Serre,Clarisse Huguenard,Gerhard Fink,Francis Taulelle,Marc Henry,Thierry Bataille,Gérard Férey,Gérard Férey +8 more
TL;DR: Analysis of the hydration process by solid-state NMR has clearly indicated that the trapped water molecules interact with the carboxylate groups through hydrogen bonds, but do not affect the hydroxyl species bridging the aluminum atoms.
Journal ArticleDOI
Double-quantum homonuclear correlation magic angle sample spinning nuclear magnetic resonance spectroscopy of dipolar-coupled quadrupolar nuclei.
TL;DR: A central-transition-selective pi pulse at the beginning of the t1 evolution period differentiates coherence transfer pathways of double-quantum coherences arising from coupled spins and from a single spin, so that the latter can be efficiently filtered out by phase cycling.
Journal ArticleDOI
71Ga Slow-CTMAS NMR and Crystal Structures of MOF-Type Gallium Carboxylates with Infinite Edge-Sharing Octahedra Chains (MIL-120 and MIL-124)
Redouane Hajjar,Christophe Volkringer,Thierry Loiseau,Nathalie Guillou,Jérôme Marrot,Gérard Férey,Irene Margiolaki,Gerhard Fink,Cláudia Morais,Francis Taulelle +9 more
TL;DR: In this paper, two gallium carboxylates of MOF-type have been synthesized by using 1,2,4,5-benzenetetracarboxylate (Ga4(OH)8[C10O8H2]·5−5.6H2O or MIL-120) or 1, 2, 4, 5 -benzenetricarboxylic acid (MIL-124) as linkers.
Journal ArticleDOI
Implementing SPAM into STMAS: A net sensitivity improvement in high-resolution NMR of quadrupolar nuclei
Jean-Paul Amoureux,Laurent Delevoye,Gerhard Fink,Francis Taulelle,Alexandrine Flambard,Lionel Montagne +5 more
TL;DR: The sensitivity, advantages and drawbacks of DQF-STMAS are compared to 3QMAS and the soft-pulse added mixing (SPAM) idea is introduced, resulting in a net sensitivity gain with respect to 2D NMR methods.
Journal ArticleDOI
Flip-back, an old trick to face highly contrasted relaxation times: Application in the characterization of pharmaceutical mixtures by CPMAS NMR
TL;DR: The application of the flip-back increases significantly the relative signal intensity of the component with the longer T(1), making this component detectable even after using short recycle delays, and could be used routinely to get (13)C CPMAS NMR spectra of mixtures in constant experimental time and signal-to-noise ratio.
