The deformation in rhodium isotopes is investigated using adiabatic and configuration-fixed constrained triaxial relativistic mean field (RMF) approaches. The triaxial deformations are found in the ground states of ${}^{102,104,106,108,110}\mathrm{Rh}$, which is consistent with triaxial Skyrme Hartree-Fock calculations. Several minima with triaxial deformation in ${}^{104,106,108,110}\mathrm{Rh}$ are obtained by the configuration-fixed constrained calculations. The corresponding configurations are characterized by the quantum numbers $|\mathit{nljm}\rangle$ obtained by transforming wave functions from a Cartesian basis to a spherical basis. The possible existence of multiple chiral doublets (MχD) is demonstrated in ${}^{104,106,108,110}\mathrm{Rh}$ isotopes, based on different particle-hole configurations and triaxial deformations.
