EPR of Mn 4ϩ has been used to study electron-phonon interactions and cation distribution in Li 1ϩx Mn 2Ϫx O 4 spinels with 0 Յ x Յ 0:1: The EPR spectra of Mn 4ϩ in 16d spinel sites has been interpreted in terms of the bottleneck-relaxation mechanism. Two additional weak signals were registered that
