Abstract

A selective TOCSY experiment based on the recently described DPFGSE selective excitation sequence has been developed: it employs gradient purging pulses which result in excellent lineshapes free of antiphase dispersive components, and has proven useful in the identification of a number of impurities in a pharmaceutical intermediate.
