Over a decade ago, the existence of long-range Rydberg molecules was first predicted.  These diatomic molecules consist of an atom excited to a high-lying Rydberg state and another atom in its ground state.  These molecules were predicted to be very large (~0.1 micrometers) and to exhibit extreme sensitivity to external fields.  Among the most remarkable predicted properties of this system is the existence of extremely large dipole moments (~ 1 kiloDebye) in homonuclear molecules.  In recent years, the first experimental evidence for these molecules has emerged, and researchers have begun the initial exploration of their dipole moments.  In this talk, I will discuss recent theoretical and experimental advances in the exploration of this exotic species of molecule, including the first direct measurement of ultra-large dipole moments in homonuclear, diatomic Cesium molecules.
