General features are calculated for excitation of non-normal parity states in pion scattering on $1p$-shell targets. Detailed distorted-wave impulse approximation results are given for ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ and related to effects of nuclear structure. Approximate formulas are deduced and applied to the region of excitation energy from 10 to 23 MeV. Calculations for ($e, e^{\prime }$) in this region are included.
