At a given ac frequency, the transmission of the guide depends on the mass-to-dipole-moment (m/\\textmu) ratio of the molecular quantum state. Here we present a detailed characterization of the m/\\textmu selector, using a pulsed beam of benzonitrile (C$_6$H$_5$CN) molecules in combination with rotational quantum state resolved detection. The arrival time distribution as well as the transverse velocity distribution of the molecules exiting the selector are measured as a function of ac frequency.
