Electromagnetically-induced transparency (EIT) in a three-level cascade configuration is examined in 85Rb(5S1/2-5P3/2-5D5/2), and two-photon EIT processes are used to resolve the hyperfine levels in the upper level of the coupling field transition. By coupling a radio-frequency field into one of these hyperfine transitions, EIT resonances corresponding to the hyperfine levels are either inhibited or enhanced, depending on the position of the hyperfine transitions in relation to the applied radio-frequency field. The roles of level splitting and three-photon resonance peaks in the resulting spectra are discussed.
