From version 2.2.1 onwards it is possible to add the spinning speed at which an experiment was recorded by going to the Experiments popup in the Experiment menu and then going to the Experiment Details tab. Analysis will then automatically add dashed side-band diagonals to your spectrum where relevant. You can also use V, H and M to draw vertical rulers, horizontal rulers or marks which are repeated at side-band intervals. This is a convenient way to identify whether for instance a peak in the aromatic region of the spectrum is in fact a side-band peak from the carbonyls or not.
