Atomization Energies of the Polymers of Germanium, Ge2to Ge7

摘要: Using information derived from a combination of effusion and mass‐spectrometric techniques at high temperature, the atomization energies free for reactions Gen(gas)=n(Ge gas) (n=2, 3, 4, 5, 6, 7) have been determined. The values energy as obtained variation with temperature (second law thermodynamics method) are in kilocalories per mole: they 65, 149, 238, 321, 407, 481 n 2, 7, respectively.
