===Details===
Varian pulse sequence, macros, selective pulse RF waveform and sample data for a simple 1D pure shift experiment. Produces a 1H spectrum in which the effects of all couplings between protons are suppressed, provided the protons are separated by more than the bandwidth of the selective pulse. Experiment and results are described in Angew. Chemie Int. Ed. 2010, 49, 3901 (DOI: 10.1002/anie.201001107) and in  Chem. Commun.207, 933-935.

Please note that this is development code. There may be incompatibilities with certain versions of Vnmr and VnmrJ. Future versions of the [[DOSYToolbox|DOSY Toolbox]] will accommodate both pureshift and [[Pure shift OneShot pulse sequence for Varian (G.A. Morris/M. Nilsson)]] data.
