摘要：

The 7F0 → 5D0 transition of EuCl63- in cubic environments in the title compounds has been studied by dye laser excitation spectroscopy. Structured vibronic origins due to the ν4, ν3 and the sodium lattice vibrations dominate the vibronic spectrum. Vibrational dispersion of ν4 and ν3 is surprisingly large at about 30 and 70 cm-1, respectively. The intensity of the sodium motion is much higher than for other 7FJ↔5DJ transitions. These observations are important in understanding energy migration in the title compounds. © 1990.
