Notes:
Mass spectra of the saturated vapour and partial pressures of different species over solid InI3 were measured between 350 and 450 K with a mass spectrometric Knudsen effusion technique. By measuring appearance energies (AE) for different ions in the mass spectra, it was proved that InI3 evaporates congruently from the solid phase as InI3(g) and In2I6(g). Values of AE for In2In+ ions (n = 0-5) increase as n decreases, showing an interesting periodicity with In—I bond strengths. For these measurements an improved deconvolution of the ionization efficiency curves by fast Fourier transformation, using a combined Maxwellian and Gaussian electron energy distribution, was performed. By measuring ion abundances as a function of temperature, the Clausius-Clapeyron plots for all ions appearing in the mass spectra were drawn.
