A theory of the excitation and conversion between multiple-quantum coherences in spin I=3/2 quadrupolar nuclei in powdered samples in the sudden-passage limit is presented. The theory is applicable to rf irradiation even at RR conditions (ω1=nωr and may be extended to include resonance offset and second-order quadropolar effects, as well as potentially generalized to the treatment of Igt;3/2 nuclei.
