Anisotropy of the induced current density (ACID), a general method to quantify and visualize electronic delocalization

The Anisotropy of the Induced Current Density (ACID) meets the conditions of the physical properties of current density, which is determined by the perturbation of the wave function by the magnetic field. ACID is derived from a quantum theoretical quantity and does not include empirical parameters that have to be fitted. It also compliments the electrostatic surface and electron density that provides information about the charge and steric interactions.
