Studies of Organically Functionalized Mesoporous Silicas Using Heteronuclear Solid-State Correlation NMR Spectroscopy under Fast Magic Angle Spinning

Highly resolved solid-state HETCOR NMR spectra between protons and low gamma nuclei (13C and 29Si) can be suitably obtained on surfaces using a “brute force” 1H−1H decoupling by MAS at rates ≥40 kHz. Despite a small rotor volume (
