The best experimental value of the heat of dissociation of H2 is that obtained by Witmer (9) by extrapolating the oscillational levels of the normal state of the molecule to dissociation. The restoring force acting on the two nuclei becomes smaller as the nuclei get farther apart, and as a result the oscillational frequency in successive oscillational states becomes smaller and smaller. For H2 in the normal state this oscillational frequency...

The Woodward-Hoffmann rules have intellectual roots that can be traced back to Wigner-Witmer correlation rules (E. Wigner and E. E. Witmer, Z. Phys. 51 [1928], 859) and general correlation-diagram concepts (R. S. Mulliken, Rev. Mod. Phys. 4 [1932], 1) as employed, e.g., by K. F. Herzfeld, Rev. Mod. Phys. 41 (1949), 527. Alternative MO... 

It is seen from the above that the energy of the molecule in the excited state must be enough to provide for the energy of dissociation, the kinetic energy of the atoms relative to each other and for the energy which is radiated as continuous spectrum. That a similar process occurs in absorption has been shown by Dieke and Hopfield. The work of Witmer on the analysis of bands in the Lyman region gives as the heat of dissociation a value of 4.34 volts and that found by Dieke and Hopfield was 4.38 volts.
