 Title: THE BAND SPECTRUM OF THE GaH MOLECULE Creators: Ginter, M. L.; Innes, K. K. Issue Date: 1960 Publisher: Ohio State University Abstract: “An extensive emission system of GaH, in the region 5200-6400 \AA, has been obtained from a King furnace containing gallium metal and hydrogen at $1500^\circ C$;. Eight bands have been measured and analyzed on the assumption that they arise from a $^{3}\Pi-X {^{1}}\Sigma$ $transition.^{1}$ The following constants have been determined ($cm^{-1})$: [FIGURE] Under the same conditions, a diffuse band system is observed between 4220 \AA and $4850 \AA^{1}$. The vibrational differences of the lower state have been found to agree with those of the ground state given above. The bands appear to be double-headed consistent with $a^{1} \Pi$; upper $state.^{1}$” Description: $^{*}$Coefficient of $(v+1/2)^{1}$ in expression for $B_{r}$. $^{1}$ H. Neuhaus, Arkiv, fur Fysik 14, 551 (1959), who also analyzed the 0-0 bands of the $^{3} \Pi_{o^{-}} {^{1}}\Sigma$ and $^{3} \Pi_{1^{-}} {^{1}}\Sigma$ systems.
