We appreciate many helpful discussions with Martin Hürlimann at Schlumberger-Doll Research.We thank Dr.Isik Kizilyalli,program director of the Advanced Research Projects Agency-Energy(ARPA-E),for the partial support of this research under contract DE-AR0001063.
We propose a four-step phase cycling scheme that can cancel ringings from both the excitation and the refocusing pulses in Carr-Purcell-Meiboom-Gill(CPMG)measurements.It allows accurate measurements of the first echo ...

NMR spectra acquired with experiments using frequency-sweeps such as the wide-band uniform-rate smooth truncation(WURST)spin-echo and Carr-Purcell-Meiboom-Gill(CPMG)sequences cannot be absorptively phased by using onl...
