Varian pulse sequence, macros, selective pulse RF waveform and sample parameters for a pure shift Oneshot DOSY experiment. Produces an array of 1H spectra 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. Once the raw data have been converted into an array of pure shift fids, they can be processed as normal to give a 2D DOSY spectrum. Experiment and results are described in a paper in press in Angew. Chemie Int. Ed., DOI: 10.1002/anie.201001107.
