摘要：

Raman spectra have been obtained for the first time from polycrystalline samples of NpO2, PuO2 and EuF2. Raman spectra were also obtained from polycrystalline samples of ThO2, UO2 and CeO2 for comparison with published results. Each of these compounds exhibits the CaF2 (fluorite)-type cubic crystal structure. The observed Raman active phonon (T2g) frequencies were used in conjunction with reported optically active IR phonon (T1u) frequencies to calculate the force constants for both the cation-anion stretching (K) and anion-anion repulsion (F). © 1990.
