Motivated by recent developments in measurements of electron spin resonances individual atoms and molecules with a scanning tunneling microscope (ESR-STM), we study transport through an impurity under periodic driving as function the parameters model junction. The consists single-orbital quantum connected to two electrodes via time-dependent hopping terms. terms are treated at lowest order perturbation theory recover Lindblad-like master equation transport. As experiment, ESR-STM signal is given variation long-time DC current frequency. density-matrix coherences play important role evaluation signal. Electron correlation included our mode. charging energy $U$ has significant influence on dynamics depending sign magnitude applied bias. Our allows direct insight into origin ESR from many-body impurity.
