The Heat of Dissociation of Carbon Monoxide

The author's method for calculating the heat of dissociation of nitrogen, has now been applied to carbon monoxide. For both ${\mathrm{N}}_2$ and CO the method agrees with the best values obtained by other methods. Using the present value of 10.3 volts for the heat of dissociation of CO, the dissociation products of the molecule are discussed for several electronic levels. In this way it is shown that the recent value of 1.3 volts for the energy of the metastable ${}_{}{}^1{}_{}{}^{}D_2^{}{}_{}{}^{}$ state in oxygen, obtained by McLennan and Crawford, agrees best with the present work.
