Dissociation Energy of Carbon Monoxide

Abstract

IN a former communication¹ we suggested 8.41 volts as the most probable value for the energy of dissociation of carbon monoxide. This was based upon a predissociation which we found in the upper level B¹ of the Angstrom bands² and in the upper level b³ of the third positive group³, at a height of 11.08 volts above the normal state of the molecule. Both predissociations we ascribed to the dissociation state ³P (oxygen) + ¹S (carbon). To fix the dissociation energy with certainty, however, it is necessary to find another place of predissociation caused by a different state of the dissociation products.
