| Research Abstract |
Intramolecular vibrational frequency of uranyl and neptunyl species in hydrate chloride melts was studied by Raman spectrometry and ab initio calculations. The Raman frequency experimentally obtained decreased with the increase of concentration of Cl in solvent chlorides. This is attributable to that hydration water molecules at the equatorial plane of actinyl are substituted by chloride ions. This was consistent with the calculation results.
