Values are collected in Table 5.4 for the electronic part of the electrostatic interaction. It is clear that this interaction will give rise either to perturbations or to predissociations depending on whether the interaction occurs between discrete states or discrete and continuum states. In the above example, concerning the N2 1IIU states of Worley s third series, it was shown that the electrostatic interaction can also give rise to autoionizations (Chapter 8). 

In Section 3.4.2, spin-orbit matrix elements are expressed, in the single-configuratioi approximation, in terms of molecular spin-orbit parameters. These molecular parameters can also be related to atomic spin-orbit parameters. In Table 5.6, some values are given for atomic spin-orbit constants, (nl). Sections 5.3.1 and 

3 describe semiempirical methods for estimating molecular spin-spin parameters and both diagonal and off-diagonal spin-orbit parameters.
