Ferroelectric domain inversion has been obtained in Nd{sup 3+} doped lithium niobate by means of direct electron beam writing. The local effects of the polarization inversion on the optical transitions of Nd{sup 3+} ions have been studied by low temperature high resolution site selective spectroscopy. Inverted regions present different axial crystal field acting over Nd{sup 3+} ions compared with noninverted (original) regions. The results can be interpreted in terms of slight shifts of Nd{sup 3+} ions along the ferroelectric c axis within the Li{sup +} octahedrons, as a result of the lattice rearrangement after the domain inversion processes.
