A comparison was made of the absorption spectra of hexahydrate and anhydrous uranyl nitrate in dioxane, acetone, and formamide, and it was found that the transition energies change in a characteristic manner. Hypsochromic shifts occurred in going from the hydrated to the anhydrous salt, the largest in dioxane amounting to 538 cm/sup -1/. The vibrational structure was the most distinct and the determination of band positions the most exact in acetone. Therefore it was concluded that in solverts with distinct vibrational structure water exerts only a very small influence on the relative position of the potential energy curves in the gound and excited states. The intensity distribution in the anhydrous salt spectrum was generally identical with that of hexahydrated uranyl nitrate. The results on anhydrous uranyl nitrate confirmed the calculation of the totally symmetric vibrations nu /sub 1/ as arithmetic mean values of the intervals between the adjacent vibrational bands.
