Pyrochlore oxides of the composition Y 2 Ti 2Ψy Zr y O 7 , with y β«Ψβ¬ 0, 0.3, 0.6, and 0.9, were studied using Raman spectroscopy. Doping with Zr Ψ4 , a homovalent ion, gradually induces the material to undergo a structural change from the perfect pyrochlore structure to a defect pyrochlore structur
a further H atom to BeH requires no additional "promotion energy". The calculated limits of error in our results arise mainly because the "interpair correlation energy", although small, is not negligible and so far can only be estimated rather than calculated. BeHz(gas) is exothermic with respect t
