A new multiple π-pulse sequence in solid-state NMR

A new phase cycling scheme is proposed for use in solid-state NMR experiments involving multiple π-pulses The phase of the sequence follows the supercycled concept proposed a decade ago for heteronuclear decoupling experiments. Both theoretical and experimental results suggest that the concept of supercycling can be used in experimentsʹ other than decoupling schemes, and may be of particular utility in novel solid-state NMR experiments for reintroduction of the dipolar interaction during magic angle spinning.
