Dissociation Energy of CuCl and Cu2Cl2 Gaseous Molecules

Using the mass spectrometric and double oven technique, the molecules CuCl(g) and Cu2Cl2(g) have been observed in the superheated vapors of cuprous chloride. From the study of the various gaseous equilibria, the atomization energies of CuCl(g) and Cu2Cl2(g), D0o(CuCl)=90.6± 1.1 and D0o(Cu2Cl2=225.8± 1.1 kcal/mole, were derived. Polymerization energies of CuCl to dimer, trimer and tetramer, and the energy of formation of Cu2Cl2(g) from trimer and tetramer were also determined.
