Miscellaneous diatomic reactions

Limited studies have been performed which give some information on energy disposal in other diatomic molecule reactions such as CH + 02 [630], CH + NO [630], NH + HN3 [631], NH + CF4, CHF3, CH2F2, CH3F [632], BrCl + CIO [633], SO + 03 [634] and SH + 03 [635].

In the following three sections we shall discuss four applications of quantum mechanics to miscellaneous problems, selected from the very large number of applications which have been made. These are the van der Waals attraction between molecules (Sec. 47), the symmetry properties of molecular wave functions (Sec. 48), statistical quantum mechanics, including the theory of the dielectric constant of a diatomic dipole gas (Sec. 49), and the energy of activation of chemical reactions (Sec. 50). With reluctance we omit mention of many other important applications, such as to the theories of the radioactive decomposition of nuclei, the structure of metals, the diffraction of electrons by gas molecules and crystals, electrode reactions in electrolysis, and heterogeneous catalysis.
