  Chemical-shift referencing
  In most cases, the chemical-shift positions of the peaks in your spectrum will be calculated automatically, and will be given in parts per million.
 
  If you need very accurate shifts, the reference should be double-checked. If you included a chemical-shift reference standard in your sample, you can calibrate the peaks in your spectrum relative to the shift defined for the standard. Or, you can refer the sample-peak positions to the position of a known peak, such as a solvent resonance.
   
  To set a chemical-shift reference in NUTS, left-click on the appropriate peak and type o while holding the mouse button down, as illustrated below (click here for a larger version). Enter the appropriate chemical-shift value when prompted.
