Based on infrared spectra and protonic conductivity measurements, we propose a model of hydrogen ion migration in K1-yLiyTa1-xNbxO3 doped crystals and use it to obtain a theoretical estimate of the diffusion constant pre-exponential factor D0 that is in reasonable agreement with the experimental result. This model shows that the transition energy of the second, and higher, overtone(s) of the [OH] vibration can be higher than the activation energy of hydrogen ion migration.
