title: [FTIR-PAS of rare earth coordinated compounds of Schiff base derived from vanillin and p-toluidine].
abstract: The Fourier transform infrared photoacoustic spectra (FTIR-PAS) of Schiff base derived from vanillin (3-methoxy-4-hydroxybenzaldehyde) and p-toluidine and its rare earth coordinated compounds in the 3800-200cm(-1) were measured and inverstigated. The coordinated compounds have two classes: [LnL2Cl x 3H2O]Cl2(Ln:La,Ce,Pr,Nd,Sm,Eu,Gd,Dy;L:Schiff base ligand) and [LnL2Cl2 x 2H2O] Cl x H2O(Ln:Ho,Er,Tm,Yb,Lu). In the coordinated compounds there is intermolecular hydrogen bond derived from phenolic hydroxy group. The bands at 400 and 300cm(-1) are respectively assigned to bonds M-O (water) and M-N.
