The nuclear Overhauser effect (NOE) was used to identify one of the amino proton resonances of base A23 in interaction with A9. These bases form a triple with U12 in the D stem of yeast tRNAPhe. The identification was verified by finding an NOE from this amino proton to the C8 proton of A9, as determined by comparisons of NOE's in a native and a C8-deuterated sample.
