Optical excitation of trivalent platinum (5d7, t6e) ions in lead titanate single crystals have been observed for the first time by electron paramagnetic resonance (EPR). The g and hyperfine coupling A tensors were found to be axial: g=1.938, g=2.478, A=0.0164 cm-1, and A=0.0324 cm -1. Analysis of the EPR spectra using crystal field theory indicates that the Pt+3 ions are in tetragonally distorted (elongated) octahedral sites, strongly suggesting that they substitute for the central Ti+4 ions in the perovskite lattice.
