triple bond
in chemistry, a covalent linkage in which two atoms share three pairs of electrons, as in the nitrogen molecule, N2. One of the electron pairs is present in a sigma bond, concentrated in the region along the line joining the two nuclei; the other two pairs are present in pi bonds, each of which occupies two parallel regions of space on opposite sides of the line determined by the two atoms.
