    • Abstract

       

      From the experimental conditions under which the spectra are obtained it is assumed that they are due to molecular radiation. Thermochemical and spectrascopic data enable one to illustrate the relation among the energy levels of the various systems in the formation of the multi-atomic molecules from their constituent atoms. Such simplified Franck-Condon diagrams are constructed for SnCl4 (which includes SnCl2) and SiCl4. An interpretation, uniform in all cases, of the observed continuous bands in terms of the transitions among the energy levels, transitions, which of course involve a repulsive state for their final level, is suggested.
