A Raman scattering study of H{sub 2} in ZnO which addresses the formation process, the thermal stability, the interaction with the phonon spectrum, the position in the host lattice, as well as the ortho-para conversion rates is presented. In particular, it is shown that the molecule is practically a free rotator stable up to 700 °C. Furthermore, an ortho-para conversion rate at 79 K was found to be 7.5 h, whereas the back conversion at room temperature occurs within less than 0.5 h. The interstitial site is suggested as the most likely position for the molecule in the ZnO lattice.
