We assess the prospect of using ring seismology to probe the interiors of theice giants Uranus and Neptune. We do this by calculating normal mode spectrafor different interior models of Uranus and Neptune using the stellaroscillation code GYRE. These spectra provide predictions of where in theseplanets' ring systems the effects of interior oscillations might be detected.We find that f-mode resonances with azimuthal order $m=2$ or $7 \leq m \leq 19$fall among the inner rings (6, 5, 4, $\alpha$, and $\beta$) of Uranus, whilef-mode resonances with $2 \leq m \leq 12$ fall in the tenuous $\zeta$ ringregion. In addition, f-mode resonances with $m=2$ or $6 \leq m \leq 13$ maygive azimuthal structure to Neptune's tenuous Galle ring. We also find thatg-mode resonances may fall in the middle to outer rings of these planets.Although an orbiter is most likely required to confirm the association betweenany waves in the rings and planetary normal modes, the diversity of normal modespectra implies that identification of just one or two modes in the rings ofUranus or Neptune would eliminate a variety of interior models, and thus aid inthe interpretation of Voyager observations and future spacecraft measurements.
