000057483 520__ $$aThe mass spectral patterns of CeCl3(g) and LuCl3(g) and appearance energies for the identified ions were measured using a Nier-type mass spectrometer coupled with a Knudsen cell. The molecular ion CeCl3+ was found to be considerably less stable in comparison to LuCl3+. Partial pressures and sublimation enthalpies of LnCl(3)(s) to monomeric LnCl(3)(g) and dimeric Ln(2)Cl(6)(g) species were obtained in the ranges of 882-1028 (Ln = Ce) and 850-1004 K (Ln = Lu). The contribution of dimeric Ce2Cl6(g) species to equilibrium vapors of CeCl3(s) is considerably smaller than the Lu2Cl6(g) contribution in LuCl3(s) vapors. The measurements were supplemented by quantum chemical ab initio studies of structures, energetics, and vibrational frequencies of neutral and singly ionized LnCl, LnCl(2), and LnCl(3) species (Ln = Ce, Lu). The theoretical appearance energies of different ions, calculated from the energies of the gaseous species, are in good agreement with experimental data. The fragmentation energies of LnCl, LnCl(2), and LnCl(3) were also computed and compared with the mass spectral patterns of respective vapor species. The Mulliken and natural bond orbital electron population methods were applied for the systematic analysis of the bonding scheme in molecules and cations.
