Moerner and Ambrose studied the light given off by single molecules of the organic compound pentacene embedded in the crystal lattice of another organic compound known as para-terphenyl.
Such jumps apparently result from local changes in the structures or positions of the molecules surrounding the impurity Because para-terphenyl molecules consist of three molecular rings linked by single bonds to form a string, one possible cause for the jumps may be sudden shifts in the central ring's tilt with respect to the two outer rings.
