Proton elastic scattering data are analyzed in the framework of a single-particle theory to obtain energies, partial widths, total widths, and spectroscopic factors for 14 isobaric analog resonances in ${}_{}{}^{131}{}_{}{}^{}\mathrm{I}$. Excitation functions and fits are presented and the results are compared with those of similar analyses as well as with those of ($d,p$) investigations. A total of 42 excited states in ${}_{}{}^{130}{}_{}{}^{}\mathrm{Te}$ were identified from the inelastic spectra at the various resonances. Groups of states at the $d_{\frac{3}{2}}$, $f_{\frac{7}{2}}$, and $p_{\frac{3}{2}}$ resonances were analyzed as neutron particle-neutron hole states, and fits to the angular-distribution data for these states are presented. The analysis provides proton partial widths, spectroscopic factors, and assignment of possible spins and parities for these states. The ${}_{}{}^{130}{}_{}{}^{}\mathrm{Te}$ inelastic results are compared with those of other nuclei in the $N=82\mathrm{}$ mass region.
