The parametrization of scalar, pseudoscalar, vector and pseudovector vertex functions in the Rarita–Schwinger basis is considered, the invariant form-factors being free of kinematical singularities and zeros. In the case of the vector vertex function the connection with the usual multipole decomposition is found.
