Low-power decoupling at high spinning frequencies in high static fields

Weingarth, MarkusBodenhausen, GeoffreyTekely, Piotr2010-06-032010-06-032010-06-03200910.1016/j.jmr.2009.04.015https://infoscience.epfl.ch/handle/20.500.14299/50625We demonstrate that heteronuclear decoupling using a Phase-Inverted Supercycled Sequence for Attenuation of Rotary Resonance (PISSARRO) is very efficient at high spinning frequencies (v(rot) = 60 kHz) and high magnetic fields (900 MHz for protons at 21 T) even with moderate radio-frequency decoupling amplitudes (v(1)' = 15 kHz), despite the wide range of isotropic chemical shifts of the protons and the increased effect of their chemical shift anisotropy.
