^*Line width was measured without line broadening for SCUS and GCUG, 20-Hz line broadening for GCAUG, and 60-Hz line broadening for GCGAUG. Values are only reported for resonances whose signal to noise allowed reliable measurements of the peak area.

^†The measurement error is estimated as 5%.

^‡Only one high signal to noise measurement is available.

^§Only two high signal to noise measurements are available.
