  • Direct 17O Isotopic Labeling of Oxides Using

     · While 17O NMR is increasingly being used for elucidating the structure and reactivity of complex molecular and materials systems much effort is still required for it to become a routine analytical technique. One of the main difficulties for its development comes from the very low natural abundance of 17O (0.04 ) which implies that isotopic labeling is generally needed prior to NMR analyses
