  The interaction potentials between vector mesons and octet baryons are
calculated explicitly with a summation of t-, s-, u-channel diagrams and a
contact term originating from the tensor interaction. Many resonances are
generated dynamically in different channels of strangeness zero by solving the
coupled-channel Lippman-Schwinger equations with the method of partial wave
analysis, and their total angular momenta are determined. The spin partners
N(1650)1/2^{-} and N(1700)3/2^-, N(1895)1/2^{-} and N(1875)3/2^-, and the state
N(2120)3/2^- are all produced respectively in the isospin I=1/2 sector. In the
isospin I=3/2 sector, the spin partners Delta(1620)1/2^- and Delta(1700)3/2^-
are also associated with the pole in the complex energy plane. According to the
calculation results, a J^P=1/2^- state around 2000 MeV is predicted as the spin
partner of N(2120)3/2^-. Some resonances are well fitted with their
counterparts listed in the newest review of Particle Data Group(PDG), while
others might stimulate the experimental observation in these energy regions in
the future.
