We demonstrate a technique for investigation of a strongly perturbed atomic system, which is an extension of standard radio-frequency spectroscopy. Analogous to `Relaxation in the Dark' experiments, this technique allows a reconstruction of the population distribution of the unperturbed atomic state by observing the rf spectroscopy signal after an abrupt switch off of the perturbing light. The evolution and relaxation dynamics of the individual magnetic sublevels is investigated. Experimental observations are supported with numerical modelling based on a full density-matrix calculation performed in the presence of spin-exchange collisions and homogeneous relaxation.
