This thesis is in three distinct parts. In Chapter II a renormalisable model of vector meson dominance is considered and it is shown that, for a correctly renormalized and diagonalized field theory, the conventional current-field identity picture of vector dominance is no longer correct. However, most of the usual results of vector meson dominance are derivable in the new formalism, which in particular provides a very neat way of calculating the hadronic contributions to the anomalous magnetic moments of the leptons. In Chapter III the usual off mass-shell extrapolation associated with vector dominance is compared with the predictions of a current algebra model. We conclude, as does Sakurai, that vector meson dominance should only be applied in the centre of mass helicity frame and not in the Gottfried-Jackson frame. Also, the results obtained from the two methods of doing hard pion current algebra are compared in detail. Finally, in Chapter IV, field theoretic calculations of the decay of a charged pion into a neutrino and lepton are carried out using the recently developed non-polynomial Lagrangian techniques and f-meson dominance.
