Abstract In this study, we aim to investigate the possibility of the manipulation of an aromatic ring current and magnetic moment induced by spin angular momentum (SAM) and orbital angular momentum (OAM) carrying light by changing the frequency of the light beam. In the study, the possibility of transitions and the contribution of the excited states into the induced current have been investigated by analyzing the angular band structure. The induced current density has been obtained by using time-dependent perturbation theory and calculations have been performed in Cartesian coordinate. The induced magnetic field is calculated by using the well-known Biot-Savart law. The result confirms the possibility of controlling the spin direction of a magnetic atom which can be located at the center of the ring-shaped molecule.
