Abstract

We calculate the tadpole equations and their solutions for a class of four-dimensional orientifolds with orbifold group Z_N \times Z_M, and we present the massless bosonic spectra of these models. Surprisingly we find no consistent solutions for the models with Z_2 \times Z_4 and Z_4 \times Z_4 orbifold groups.
