 note = {We have measured the infrared reflectivity of single-crystalline samples of LaCo1−x RhxO3 (x=0, 0.05 and 0.10) from 10 to 300 K from 0.05 to 0.15 eV. We find that the optical phonons of the Co-O stretching mode depend on temperature and the Rh content. Analysis with three Lorentz oscillators reveals that the spin state of Co^3+ in LaCo1−x RhxO3 can be understood in terms of a solid solution of low-spin- and high-spin-state Co^3+ ions, and the substituted Rh ion retains some fraction of the high-spin Co^3+ ions down to low temperature.},
