Magic-Angle Spinning Sideband Elimination by Temporary Interruption of the Chemical Shift

摘要: Abstract We introduce a new family of pulse sequences, which have the effect suppressing rotational sidebands in magic-angle spinning spectra. The sequences are based on principle evolution magnetization during certain timed fractions rotor cycle. Evolution intervening intervals causes destructive interference Fourier components lead to sidebands. is suppressed using pairs hard RF pulses equal intensities and opposite phase. shorter more robust than previous methods, can be designed incorporate refocusing pulses. Experimental details, examples, criteria for optimization provided.
