An analytic theory has been developed to simulate the nuclear modulations arising from the application of the two‐pulse electron‐spin‐echo envelope modulation (ESEEM) technique to a high‐spin‐electron system with S=5/2, coupled both to its own nuclear spin, I’=5/2, and a distant nuclear spin, I=1/2. This theory differs from that previously used by Mims [Electron Paramagnetic Resonance, edited by S. Geschwind (Plenum, New York, 1972), pp. 263–351] to describe the ESEEM results of a simpler system (S=1/2, I=1/2) by the inclusion of a zero‐field splitting (ZFS) term in the spin Hamiltonian. The major assumption made in the derivation is that only transitions that do not share a common electron energy level are excited. This and other assumptions are discussed. The resulting analytic form suggests that each of the five possible single‐quantum electron transitions in the S=5/2 system make a contribution to the ESEEM spectrum. The contribution from each electron transition is similar to that described by Mims f...
