Abstract
An acquisition method for multi-dimensional Fourier transform NMR data allows efficient accumulation of the data and provides artifact suppression in the acquired data under many circumstances. The method comprises performing an excitation pulse sequence having at least one evolution period wherein excited nuclei will at least partially relax. A transient generated from the pulse sequence is collected and stored, and the sequence is repeated with the evolution period varied in a predetermined manner. Transient information is collected for all values of the evolution period, and then the phase of at least on RF pulse may be varied and the procedure repeated. Subsequently transient information having common evolution periods may be signal averaged to obtain the NMR data. The method avoids residual magnetization effects under many circumstances, and significantly reduces acquisition time for data collection in spectroscopy or imaging environments.
