LONG RANGE ANALYSIS OF THE $G^{1}\Pi_{g}$ AND $A^{1}{\Sigma_{u}}^{+}$ STATES OF $^{7}LI_{2}$

Abstract

Using Optical-Optical Double Resonance spectroscopy 19 new vibrational levels up to v = 48 have been observed in the $G^{1}\Pi_{g}$ state of $^{7}Li_{2}$. This represents more then 99% of the potential well. From these observations a long range potential curve has been determined. The $A^{1}{\Sigma_{u}}^{+}$ state has been studied using All-Optical Triple Resonance. Vibrational levels as high as v = 50 have been observed which represents 92% of the potential well. A potential curve has also been calculated for this state.
