Abstract
The triplet Rydberg states of $^{7}Li_{2}$ have been studied by pulsed perturbation facilitated optical-optical double resonance (PFOODR) fluorescence excitation spectroscopy via three mixed $A\Sigma^{+}_{u} \sim b_{3}\Pi_{u}$ intermediate levels. 21 vibrational levels of the $2^{3}\Pi_{g}$ state. 6 vibrational levels of the $1^{3}\Delta_{g}$ state, and more than 40 PFOODR transitions into other triplet Rydberg states have been observed. Molecular constants and RKR potential energy curve of the $^{7}Li_{2} 2^{3}\Pi_{g}$ state have been obtained.
