摘要：
Electronic absorption spectra of uranium(V) dioxochloro-ions were recorded in a range of alkali chloride melts at 350-850 degrees C. The effect of temperature and second coordination sphere on the electronic transitions in UO2Cl43- ions were analyzed. Temperature has a relatively minor effect on the band positions in the spectra. The effect of the cationic composition of the melt is more pronounced and the energies of phi(5u) -> 3 pi(1u) and phi(5u) -> 3 pi(3u) transitions shift to the higher values with increasing radii of the solvent melt cations.
