Using a {ital G}-matrix folded diagram method and the Bonn nucleon-nucleon potential, the {ital s}-{ital d} shell effective interaction is derived and applied to evaluate the spectra of some light {ital sd}-shell nuclei. Due to the relatively weak tensor-force characteristic for the Bonn potential, the effective interaction matrix elements, particularly those with isospin {ital T}=0, come out generally more attractive than in earlier derivations in which local, strong tensor-force potentials were used. As a consequence of this, our results for the effective interaction and the spectra are in considerably better agreement with empirical determinations and experimental data. The sensitivity of the above nuclear structure calculations to the strength of the nuclear tensor force is demonstrated systematically and the dependence of the {ital s}-{ital d} shell matrix elements on the nuclear mass number is studied.
