AB  - Strontium titanate is a model quantum paraelectric in which in the region of dominating quantum statistics the ferroelectric instability is inhibited due to nearly complete compensation of the harmonic contribution into ferroelectric soft mode frequency by the zero-point motion contribution. The enhancement of atomic masses by the substitution of <sup>18</sup>O for <sup>16</sup>O decreases the zero-point atomic motion and low-T ferroelectricity in SrTi<sup>18</sup>O<sub>3</sub> is realized. In this study we report on the local structure of Ti in SrTi<sup>16</sup>O<sub>3</sub> and SrTi<sup>18</sup>O<sub>3</sub> by Ti K-edge extended x-ray absorption fine structure measurements in temperature range 6 – 300 K.
