What if your samples do not have deuterated solvent

If your samples do not have deuterated solvent, you should run your spectra in unlocked state.  In bsmsdisp, uncheck lock (make the button white), then go to “lock” tab and uncheck “sweep on-off” button.

The spectra will not be of the highest resolution because you will not be able to shim using the 2H lock signal.  If resolution is a concern to you, you can shim by watching the FID.
