Solid-state NMR measurements and DFT calculations of the magnetic shielding tensors of protons of water trapped in barium chlorate monohydrate

Geoffrey Bodenhausen, Diego Carnevale

The magnetic shielding tensors of protons of water in barium chlorate monohydrate are investigated at room temperature by means of solid-state NMR spectroscopy, both for static powders and under magic-angle spinning conditions, using one- and two-dimension ...

Solid-state carbon-13 NMR and computational characterization of the N719 ruthenium sensitizer adsorbed on TiO2 nanoparticles

Michael Graetzel, Geoffrey Bodenhausen, Diego Carnevale, Nicola Salvi, Julien Edouard Frey

The ruthenium-containing sensitizing dye N719 grafted on TiO2 nanoparticles was investigated by solidstate NMR. The carbon resonances are assigned by means of 13C cross-polarized dipolar dephasing experiments. DFT calculations of the carbon magnetic shield ...

Solid-state NMR enhanced by dynamic nuclear polarization as a novel tool for ribosome structural biology

Geoffrey Bodenhausen, Diego Carnevale, Marc Anthony Caporini

The impact of Nuclear Magnetic Resonance (NMR) on studies of large macromolecular complexes hinges on improvements in sensitivity and resolution. Dynamic nuclear polarization (DNP) in the solid state can offer improved sensitivity, provided sample preparat ...

How to Tickle Spins with a Fourier Transform NMR Spectrometer

Geoffrey Bodenhausen, Diego Carnevale

In the long bygone days of continuous-wave nuclear magnetic resonance (NMR) spectroscopy, a selected transition within a multiplet of a high-resolution spectrum could be irradiated by a highly selective continuous-wave (CW) radio-frequency (rf) field with ...

Broadband excitation in solid-state NMR using interleaved DANTE pulse trains with N pulses per rotor period

Geoffrey Bodenhausen, Diego Carnevale, Simone Ulzega

We analyze the direct excitation of wide one-dimensional spectra of nuclei with spin I = 1/2 or 1 in rotating solids submitted to pulse trains in the manner of Delays Alternating with Nutations for Tailored Excitation (DANTE), either with one short rotor-s ...

Analysis of sensitivity enhancement by dynamic nuclear polarization in solid-state NMR: a case study of functionalized mesoporous materials

Geoffrey Bodenhausen, Diego Carnevale

We systematically studied the enhancement factor (per scan) and the sensitivity enhancement (per unit time) in C-13 and Si-29 cross-polarization magic angle spinning (CP-MAS) NMR boosted by dynamic nuclear polarization (DNP) of functionalized mesoporous si ...

Mesoporous Silica Nanoparticles Loaded with Surfactant: Low Temperature Magic Angle Spinning C-13 and Si-29 NMR Enhanced by Dynamic Nuclear Polarization

Geoffrey Bodenhausen, Diego Carnevale

We show that dynamic nuclear polarization (DNP) can be used to enhance NMR signals of C-13 and Si-29 nuclei located in mesoporous organic/inorganic hybrid materials, at several hundreds of nanometers from stable radicals (TOTAPOL) trapped in the surroundin ...

Solid-state proton NMR of paramagnetic metal complexes: DANTE spin echoes for selective excitation in inhomogeneously broadened lines

Geoffrey Bodenhausen, Diego Carnevale, Gerald Bauer, Angel Joaquin Perez Linde

The paramagnetic complex bis(oxazolinylphenyl)amine-Fe(III)Cl-2 is investigated by means of solid-state proton NMR at 18.8 T (800 MHz) using magic-angle spinning at 65 kHz. Spin echoes that are excited and refocused by combs of rotor-synchronized pulses in ...

Broadband excitation in solid-state NMR of paramagnetic samples using Delays Alternating with Nutation for Tailored Excitation ('Para-DANTE')

Geoffrey Bodenhausen, Diego Carnevale

This Letter shows that interleaved sequences of short pulses in the manner of 'Delays Alternating with Nutation for Tailored Excitation' (DANTE) with N = 1,2,3 . . . equidistant pulses per rotor period extending over K rotor periods can be used to excite, ...
