n. Physics A pair of electric charges or magnetic poles, of equal magnitude but of opposite sign or polarity, separated by a small distance.

n. Chemistry A molecule having two such charges or poles.

n. Electronics An antenna, usually fed from the center, consisting of two equal rods extending outward in a straight line.

n. any object (such as a magnet, polar molecule or antenna), that is oppositely charged at two points (or poles)

n. any molecule or radical that has delocalised positive and negative charges

n. a dipole antenna

n. a pair of equal and opposite electric charges or magnetic poles separated by a small distance

n. an aerial half a wavelength long consisting of two rods connected to a transmission line at the center

"Another strategy was to create "electrochromic dyes" with large changes in dipole moment between ground and excited state, so that a change in neuronal membrane potential could shift the peak wavelengths of absorbance or fluorescence4."
