Abstract

Two-dimensional Fourier transform ESR has now been extended to the slow-motional and rigid limit regimes which require spectral bandwidths of 200-250 MHz and sub-nanosecond time resolution in echo decays. Two-pulse SECSY-ESR on nitroxides is shown to provide detailed structural information from the effects of nuclear modulation and slow-motional information from both the main ESR spectrum as well as the nuclear modulation.
