Excitation functions for proton elastic and inelastic scattering to several low-lying states of ${}_{}{}^{96}{}_{}{}^{}\mathrm{Mo}$ have been measured in the energy range from 5.2 to 8.0 MeV. Isobaric analog resonances have been used to deduce the structure of parent states in ${}_{}{}^{97}{}_{}{}^{}\mathrm{Mo}$. In particular, the ground state of ${}_{}{}^{97}{}_{}{}^{}\mathrm{Mo}$ was found to have parentage in four excited states of ${}_{}{}^{96}{}_{}{}^{}\mathrm{Mo}$, besides the ${}_{}{}^{96}{}_{}{}^{}\mathrm{Mo}$ ground-state component already known from ${}_{}{}^{96}{}_{}{}^{}\mathrm{Mo}\mathrm{}(d,p)\mathrm{}$ studies. Angular distributions were measured on the prominent resonances to determine the angular momenta of the exiting protons and to obtain inelastic partial widths. Noticeable asymmetries in the inelastic yield curves are found and interpreted as arising from interference between the resonance reaction and other (direct) processes. The assignment of spin-parity $0^{+}$ to the 1.15-MeV state of ${}_{}{}^{96}{}_{}{}^{}\mathrm{Mo}$ is found to be consistent with the present data.
