Coordination Behavior of Rare Earth Ion in N-Methylacetamide Solution at Low Temperatures(Papers presented at the 53rd Annual Meeting)

Abstract

We have investigated the coordination behavior of the rare earth (Ln^<3+>) ion in N-methylaceatmide (NMA) solution at 77 K by a Raman spectroscopy. Series behavior of the symmetric Raman Ln-Cl stretching band (v_<Ln-Cl>) and the Raman amide III band (v_<AIII>) of the NMA is discussed in conjunction with the coordination number change in the middle of the series. It is concluded that the elimination of NMA molecule induces the coordination number change of the Ln^<3+> ion.
