    "abstract": "A method of creating pseudopure spin states in large clusters of coupled\nspins is described. It is based on filtering multiple-quantum coherence of the\nhighest order followed by a time-reversal period and partial saturation.\nExperimental demonstration is presented for a cluster of six dipolar-coupled\nproton spins of a benzene molecule in liquid crystalline matrix, and the\ndetails of spin dynamics are studied numerically.",
