Abstract
Two low-lying Rydberg states of $K_{2}$ have been observed using high resolution optical optical double resonance spectroscopy. The absolute vibrational assignments hive been done by comparing the excitation and resolved fluorescence intensities with the Franck Condon Factors calculated from Rydberg-Klein-Rees potential curves derived from fitted Dunham molecular constants. The atomic asymptotic assignments of the molecular Rydberg states have been done by comparing the molecular potential well separations with the correlated atomic energy separations. Bonding and antibonding characteristics of $^{1}{\Delta}_{g}$ and $^{1}\Pi_{g}$ be discussed.
