Abstract

Ion-pair states of the I$_2$molecule have been the subject of many experimentals studies and to date all 18 states correlating with I$^+$($^3$P$_{J=2,1,0}$, $^1$D$_2$) + I$^-$($^1$S$_0$) asymptotes are known from experiment. This contribution reports on \textit {ab initio} study of the I$_2$ molecule with an emphasis on the ion-pair states. Figure shows experimental and calculated potentials of the ion-pair states correlating with I$^+$($^3$P$_{2}$) + I$^-$($^1$S$_0$) asymptote (energy is relative to I ($^2$P$_{3/2}$) + I ($^2$P$_{3/2}$) asymptote).
