Add to ORKGSmall silicon carbides are of particular interest to the astrochemical community given the appearance of SiC, SiC$_2$, Si$_2$C, and SiC$_3$ in the interstellar medium. Here, we report high resolution anion photoelectron spectra of cryogenically cooled SiC$_3^{-}$, Si$_2$C$_2^{-}$, and Si$_3$C$^-$, providing new insight into the geometric and vibronic structure of the corresponding neutral radicals. Comparison to theory suggests the anionic ground states for all three species are ring structures, with the ground state of Si$_2$C$_2^-$ being a distorted rhombic structure possessing a dipole moment. Detachment from these anions yield vibrational frequencies for the three neutral ring structures, with a number of Franck-Condon forbidden transit...
