    • This is the minimum phase cycling for I = 3/2 nuclei, and 6-fold phase cycling is needed in the third pulse for the case of I = 5/2 nuclei to suppress the coherence transfer to -1 from not only triple-quantum but also quintuple-quantum coherence.

    • 0 in the denominator of the second term is a sufficiently good approximation, which gives faster line-shape calculation under the constraint.
