Thermochemical data for the lanthanide monohalides have been combined with recent ligand field theory calculations (A. L. Kaledin, M. C. Heaven, R. W. Field, and L. A. Kaledin (1996). J. Mol. Spectrosc. 179, 310) to estimate the dissociation energies and ionization potentials for all LnX (where Ln Κ¦
