We analyze D{r_arrow}PV, D{r_arrow}PP, and D{r_arrow}VV decays within a model developed to describe the semileptonic decays D{r_arrow}Vl{nu}{sub l} and D{r_arrow}Pl{nu}{sub l}. This model combines the heavy quark effective Lagrangian and chiral perturbation theory. We determine amplitudes for decays in which the direct weak annihilation of the initial D meson is absent or negligible, and in which the final state interactions are small. This analysis reduces the arbitrariness in the choice of model parameters. The calculated decay widths are in good agreement with the experimental results. {copyright} {ital 1997} {ital The American Physical Society}
