The absorption spectrum of Bk(III) in a lanthanum chloride host matrix at 77 K was first obtained in 1964 (102). A prediction of the energy level structure of Bk(III) was made by others the same year (103). Extensive, low-temperature spectroscopic studies of BkCl3 showed the absence of transitions to excited J = 0 and J = 1 states (104, 105). This provided good evidence for a fi = 0 ground level for Bk(III), consistent with that of Tb(III)-LaCl3 (106). Experimental and theoretical studies of the crystal field parameters of Bk(III) in a LaCl3 host lattice have also been reported (107). 

Atomic spectrometric tests in air/acetylene flames a number of ions (like phosphate, sulphate, aluminium) decrease the emission and absorption signals of barium (and all of the alkaline earth metals). Adding an equal volume of a 25% solution of lanthanum chloride heptahydrate LaCl3 7H2O eliminates these interferences. Addition of lanthanum is not required if the nitrous oxide/acetylene flame is used.

In other words, the diffusion of the lanthanum chloride is 0.62 10 cm /sec, which is the same as the solitary ion. Thus the diffusion of dilute LaCl3 in concentrated NaCl is dominated by the diffusion of the uncommon ion, La ... 

The electronic structure and chemical bonding in the 15-crown-5 complex of lanthanum trichloride having a coordination number of 8 has been studied. The molecular structure of LaCl3(15-crown-5) and the charge distribution of the complex, ligand and metal chloride are shown in Figs 5.23 and 5.24, respectively.
