Microcoil high-resolution magic angle spinning NMR spectroscopy.
We report the construction of a dual-channel microcoil nuclear magnetic resonance probehead allowing magic-angle spinning for mass-limited samples. With coils down to 235 mum inner diameter, this allows high-resolution solid-state NMR spectra to be obtained for amounts of materials of a few nanoliters. This is demonstrated by the carbon-13 spectrum of a tripeptide and a single silk rod, prepare...
متن کاملUltrafast high-resolution magic-angle-spinning NMR spectroscopy.
We demonstrate the acquisition of ultrafast 2D NMR spectra of semi-solid samples, with a high-resolution magic-angle-spinning setup. Using a recent double-quantum NMR pulse sequence in optimised synchronisation conditions, high-quality 2D spectra can be recorded for a sample under magic-angle spinning. An illustration is given with a semi-solid sample of banana pulp.
متن کاملEnvironmental NMR: High-resolution Magic-angle Spinning
Environmentally significant materials including soils, plant tissues, melanin pigments, and urban surface films possess swollen or swellable constituents that are not studied ideally using either solutionor solid-state NMR. Beginning in the 1970s and accelerating during the past 15 years, high-resolution (HR)-MAS techniques have been developed to study these challenging materials, yielding unpr...
متن کاملHigh-resolution (1)H NMR spectroscopy in organs and tissues using slow magic angle spinning.
It is shown that high-resolution (1)H NMR spectra of intact excised tissues and organs can be obtained by rotating the sample slowly about an axis at the magic angle of 54 degrees 44' with the external magnetic field. In this way tissue and cellular damage invoked by standard magic angle spinning (MAS) experiments, where spinning speeds of several kHz are typically employed, are minimized. Spec...
متن کاملHigh-resolution oxygen-17 NMR spectroscopy of solids by multiple-quantum magic-angle-spinning
High-resolution solid state nTo NMR spectra of nTo-enficbed compounds were observed with multiple-quantum magic-angle-spinning (MQMAS) experiments. The resolution of the 170 MQMAS spectra is approximately 30to 150-fold higher than that found in conventional 170 MAS spectra, making it possible to detect crystallographically distinct oxygen sites. It is shown that into MQMAS studies are feasible ...
