The Raman-shifted output of a single YAG-pumped dye laser has been used to produce two-photon transitions from the ground $X1\Sigma \mathrm{<mrow\; data-mjx-texclass="ORD">+</mrow>}g$ state to the $21\Sigma \mathrm{<mrow\; data-mjx-texclass="ORD">+</mrow>}g$ state to the $\mathrm{<mrow\; data-mjx-texclass="ORD">7</mrow>}Li2.$ The lower vibrational levels of this excited state have been studied by Barakat $etal.1$; our work extends the measurements to the dissociation limit at $v=24$. The molecular constants and potential curve will be presented.
