The RAFFn pulses are designed to generate fictitious
fields that allow locking of magnetization in the
rotating frames of rank n. Exchange induced relaxations
during RAFFn pulses for two site exchange were described
using Bloch-McConnell formalism. The results demonstrate
that with the increase of n the sensitivity of RAFFn to
the slow motional regime increases.
