  "abstract": "We investigate the interactions and chiral properties of the four spin-$\\thalf$-baryons : $N^-(D_{13})$, $N^+(P_{13})$, $\\Delta^+(P_{33})$ and $\\Delta^-(D_{33})$ together with the nucleon. We construct the $SU(2)_R \\times SU(2)_L$ invariant interactions between the spin-$\\half$ and -$\\thalf$ baryons with the aid of a new, specially developed spin and isospin projection technique for these baryon fields, where the chiral invariant interactions contain one- and two-pion couplings. We obtain simple relations for the coupling constants of the one- and two-pion spin $\\half-\\thalf$ transitions terms. The relation for the one-pion interactions reasonably agrees with the experiments, which suggests that these spin-$\\thalf$ baryons are chiral partners.",
