The setting up of a potential theory applicable to isotropic chiral media (D= in E+ beta in *E, B= mu H+ beta mu *H) by the specification of vector as well as scalar, magnetic and electric potentials, is reported here. An infinite medium Green dyadic for these potentials is derived and is shown to contain two transverse components as well as a longitudinal one. The vector potentials are trirefringent; however, their longitudinal components do not contribute to the field vectors, which are only birefringent. Moreover, the vector potentials are axial vectors only for achiral media ( beta =0).
