For 10 points, name this configuration of charges, which can be modeled as a positive charge separated from a negative one.
The earliest type of antennas invented by Hertz created one of these configurations between ends of a wire attached at the center to a feed-driven elememnt. The power radiated by an oscillating one of these is proportional to the fourth power of the angular frequency divided by the speed of light cubed, and a molecule must be one of these along some axis if it is IR active. Their field intensity drops off as the inverse cube of the distance, and van Der Waals forces occur between spontaneously created ones.
