  Measurement and analysis of the temperature and pressure dependence of the 7F0→5D0 excitation spectra of Eu(III) complexes with 4-phenylethynyl-2,6-pyridine-dicarboxylic acid

  摘要：

  The pressure and temperature dependence of the D-5(0)-->F-7(0) transition of Eu(III) in complexes with 4-phenylethynyl-2,6-pyridinedicarboxylic acid has been measured at various metal to ligand ratios. The spectra have been fit to a sum of Lorentzian peaks, and the temperature dependence used to determine Delta H for the equilibrium reaction for formation of the tris complex from the bis complex. The pressure dependence of the D-5(0)-->F-7(0) transitions corresponding to the bis and tris species is analyzed in order to determine the associated difference in volume, Delta V, between reactants and products.
