      abstract     = {In this work we report on the local structure of Ti in
                      SrTi$^{16}$O$_{3}$ (STO16) and SrTi$^{18}$O$_{3}$ (STO18)
                      investigated in the low temperature range (6–300 K) by
                      extended x-ray absorption fine structure and x-ray
                      absorption near edge structure (XANES) spectroscopy at Ti
                      K-edge and by optical second harmonic generation (SHG). By
                      comparing XANES of STO16 and STO18 we have identified the
                      isotopic effect which produces at T < 100K a noticeable
                      difference in the measured mean square relative
                      displacements (MSRD) of Ti–O1 bonds: while STO16 follow
                      the expected Einstein-like behavior, for STO18 we have
                      measured an increase of MSRD values with decreasing
                      temperature. This is an indication of an increasing
                      off-center position of the Ti atoms in the TiO$_{6}$
                      octahedra.},
