Abstract

An NMR technique to measure pure-phase two-dimensional nutation NMR spectra, that yields higher resolution than traditional nutation experiments is reported. Using this technique 93Nb" role="presentation" style="box-sizing: border-box; margin: 0px; padding: 0px; display: inline-block; line-height: normal; font-size: 16.2px; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; position: relative;">93Nb nutation NMR spectra of PbNb2O6 and the technologically important Pb(Mg1/3Nb2/3)O3 (PMN) have been measured and the quadrupolar coupling constant of the niobium site in PbNb2O6 (CQ=19±2 MHz) determined. Estimates of the quadrupolar coupling constants for three different resonances associated with different niobium(V) sites in PMN (CQ62 MHz) are also reported.
