1H homonuclear dipolar decoupling using rotor-synchronised pulse sequences: Towards pure absorption phase spectra

1H homonuclear dipolar decoupling using rotor-synchronised pulse sequences: Towards pure absorption phase spectra
1H homonuclear dipolar decoupling using rotor-synchronised pulse sequences: Towards pure absorption phase spectra
We demonstrate a pulse sequence using symmetry-based rotor-synchronised sequences for homonuclear dipolar decoupling that achieves pure absorption phase high-resolution 1H spectra in solid-state NMR. This sequence is compared with the phase-modulated Lee-Goldburg scheme. Experimental results are shown for samples of glycine and l-histidine·HCl·H2O for magic-angle-spinning frequencies in the range of 14–30 kHz and at two different magnetic fields.

Abstract

We demonstrate a pulse sequence using symmetry-based rotor-synchronised sequences for homonuclear dipolar decoupling that achieves pure absorption phase high-resolution 1H spectra in solid-state NMR. This sequence is compared with the phase-modulated Lee-Goldburg scheme. Experimental results are shown for samples of glycine and l-histidine·HCl·H2O for magic-angle-spinning frequencies in the range of 14–30 kHz and at two different magnetic fields.
