Two types of spectra were obtained on lithium halides, one with essentially the saturated vapor, the other with superheated vapor. Dimer and monomer spectra were derived. The first ionization potential (IP) of dimer is higher than that of monomer in each lithium halide. Calculations predict that trimer has lower IP than dimer, and tetramer has higher IP than trimer. Electron impact measurements on LiF agree with this oscillatory trend, through trimer. A crude ionic model calculation can also rationalize this behavior (assuming hexagonal trimer and distorted cube for tetramer).
