The ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^3{}_{}{}^{}\mathrm{He}, d){}_{}{}^{13}{}_{}{}^{}\mathrm{N}$ stripping reaction has been studied at 43.6 MeV for all states of ${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$ up to 10.78 MeV. Reliable spectroscopic factors are extracted for the low-spin states. The 7.16 MeV ($\frac{7}{2^{+}}$) and 7.38 MeV ($\frac{5}{2^{-}}$) states are shown to be populated by sequential scattering to the quadrupole states and $d_{\frac{5}{2}}$ or $p_{\frac{1}{2}}$ stripping in a rotational model. The data for a state at 9.0 MeV are shown to be accounted for within the same model for a $\frac{9}{2^{+}}$ spin assignment, confirming the results of pion scattering experiments to the analogous 9.50 MeV state in ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$.
