Radial distribution of electron density in lanthanide atoms and observable lanthanide compression

Radial distribution of electron density in lanthanide atoms and observable lanthanide compression. Krasnov, K. S.; Giricheva, N. I.; Girichev, G. V. (Ivanov. Khim.-Tekhnol. Inst., Ivanovo, USSR). Zh. Strukt. Khim., 17(4), 667-70 (Russian) 1976. CODEN: ZSTKAI. DOCUMENT TYPE: Journal CA Section: 65 (General Physical Chemistry) Section cross-reference(s): 75 The metal-halogen bond lengths for gaseous LuCl3, LaBr3, GdBr3, and LuBr3 were detd. by electron diffraction. The data were compared with quantum mech. orbital radii, electronic densities, and the electron configuration of the lanthanide atoms and ions. The exptl. value for the lanthanide contraction .DELTA.(La-Lu) coincided with the values calcd. from the electronic structure of the lanthanide atoms and ions. The metal-halogen bond lengths for the remaining lanthanide trihalide mols. were estd. from a comparison of the calcd. and exptl. values of .DELTA..Except for chemicals metioned above, 13536-79-3 and 13760-81-1 are also used. .

A comparative investigation on the thermodynamics of vaporization of lanthanum fluoride and lutetium fluoride

A comparative investigation on the thermodynamics of vaporization of lanthanum fluoride and lutetium fluoride. Petzel, T.; Marx, V.; Potthast, J.; Ahnen, T. (Inst. Werkstofftecth., Univ. Bundeswehr, Hamburg W-2000/70, Germany). Thermochim. Acta, 194, 319-27 (English) 1992. CODEN: THACAS. ISSN: 0040-6031. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Section cross-reference(s): 65 The vapor pressure curves of LaF3(s) and LuF3(l) were measured by the Knudsen effusion wt. loss method using carefully calibrated molybdenum and graphite Knudsen cells. Second and third law extrapolations yielded the std. enthalpies and entropies of vaporization. The results are critically compared with the data from the literature. An addnl. third law treatment led to enthalpies of vaporization at 1500 K for both trifluorides in the liq. state. The difference at 1500 K is found to be in reasonable agreement with a corresponding result from the literature, derived from relative vapor pressure measurements on liq. 13760-81-1 and 13709-38-1 are just another two chemicals used in this study. lanthanoid trifluoride mixts. .
