Abstract

Mass spectrometric technique has been employed to analyze the molecular beams effusing from mullite Knudsen cells containing Sn and alloys of Cu, Ag, and Au with Sn. From the experimental intensities of monatomic and diatomic species and the vapor pressure of Sn, the following dissociation energies are obtained:

\begin{matrix} D_{0}^{\circ} ({Sn}_{2})=45.8±4 kcal / mole, \\ D_{0}^{\circ} (AgSn)=31.6±5 kcal / mole, \\ D_{0}^{\circ} (AuSn)=57.5±4 kcal / mole, \\ D_{0}^{\circ} (CuSn)=41.4±4 kcal / mole . \end{matrix}
