Elastic and inelastic proton scattering on ${}_{}{}^{98}{}_{}{}^{}\mathrm{Mo}$ was performed over the region of excitation of isobaric analog resonances to investigate the nature of the first two excited states of ${}_{}{}^{98}{}_{}{}^{}\mathrm{Mo}$ at 0.736 MeV ($0^{+}$) and 0.787 MeV ($2^{+}$). The experiment allowed the determination of spectroscopic factors for states in ${}_{}{}^{99}{}_{}{}^{}\mathrm{Mo}$ relative to these two excited core states in ${}_{}{}^{98}{}_{}{}^{}\mathrm{Mo}$. Spectroscopic factors extracted from the elastic data are appreciably smaller than the corresponding ($d, p$) spectroscopic factors. Angular distributions taken on the inelastic scattering resonances are used to determine the $j$ value in the exit channel. The 0.736-MeV ($0^{+}$) and 0.787-MeV ($2^{+}$) states of ${}_{}{}^{98}{}_{}{}^{}\mathrm{Mo}$ are not found to be "good" core states for weak coupling.
