Abstract
The presence of dimers in the vapor of metal dihalides, as seen in ele ctron diffraction experiments, is found to be correlated with the crys tal structure of the halide and with the difference in the heat of vap orization between monomers and dimers. If the dimeric molecule cannot be recognized as a unit in the crystal, dimers are not detected in the vapor. If dimeric molecules are discernible in the crystal, they will be observed in the vapor if their heat of vaporization is not greater than that of the monomer by more than 10 kcal/mol.
