The absorption spectrum of the A-X band system of $\mathrm{<mrow\; data-mjx-texclass="ORD">6</mrow>}Li2$ has been examined using a Bomem DA3.002 Fourier Transform Interferometer in the frequency range of $14200-17200cm-1$. A high resolution $(0.01cm-1$) spectrum was measured at two different temperatures (600 and $830\circ C$) in a heat pipe overn containing helium as a buffer gas. The spectrum was analyzed to yield Dunham coefficients and Franck-Condon factors. The molecular constants calculated for $\mathrm{<mrow\; data-mjx-texclass="ORD">6</mrow>}Li2$ are compared with those for $\mathrm{<mrow\; data-mjx-texclass="ORD">7</mrow>}Li2$.
