Elimination of the baseline distortions in WURST-CPMG static experiments

Elimination of the baseline distortions in WURST-CPMG static experiments

The WURST-CPMG pulse sequence enables: (i) observing very broad spectra due to WURST excitation, and (ii) increasing the S/N ratio due to CPMG acquisition. However, strong baseline distortions may be observed, which make the extraction of the tensor information difficult. We propose a slight modific...

description The WURST-CPMG pulse sequence enables: (i) observing very broad spectra due to WURST excitation, and (ii) increasing the S/N ratio due to CPMG acquisition. However, strong baseline distortions may be observed, which make the extraction of the tensor information difficult. We propose a slight modification of the sequence, WURST-CPMGM, in which we skip the first M echoes and we only acquire the following ones. This simple treatment mostly eliminates the strong background signal and the ring down effects, leading to a flat baseline. [Display omitted] •WURST-CPMGM: skip the first M echoes and only acquire the following ones.•WURST-CPMGM could eliminate the strong background signal.
