abstract = {The 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.},
