The structure of low lying levels in ${}_{}{}^{99}{}_{}{}^{}\mathrm{Rh}$ and ${}_{}{}^{101}{}_{}{}^{}\mathrm{Rh}$ has been investigated with the (p,$\mathrm{n}\gamma$) reaction employing $\gamma$-ray spectroscopy techniques. Many new levels in both nuclei are proposed on the basis of $\gamma -\gamma$ coincidence data. Spin assignments for several levels have been determined from excitation function and angular distribution data. The results are compared to previous work and to the available theoretical calculations.
