Mn4+, Cr3+, and Fe3+ electron paramagnetic resonance and 47,49Ti and 207Pb nuclear magnetic resonance (NMR) measurements are carried out in PbTiO3 single crystals at temperatures from 300 K down to 20 K. Experimental data indicate proximity of a transition to another phase with barely perceptible crystal-structure modification as reported in the paper by Kobayashi et al. [Phys. Rev. B28, 3866 (1983)] while, actually, it was not detected in NMR. The experimental data are compared with those obtained from ab initio calculations.
