Vibrational spectroscopy of actinyl complexes

Vibrational spectroscopy potentially provides structural information of molecule complexes. Actinyl ions can be identified by the frequency of their antisymmetric stretching vibrational mode which generally correlates with the character of the molecular environment of the actinyl ion group.
In this study the sorption behavior and the formed complexes of Uranium(VI) on gibbsite in inert gas and ambient atmosphere were analyzed by means of ATR FT-IR spectroscopy.
