Inspecting the FID
While in the time domain, you can change the amplification factor, but you cannot zoom. The FID is shown in its entirety. If you want to inspect a region of the FID more closely, choose Process > Fourier Transform and click the “fake” button. No processing is performed, but iNMR will believe that the spectrum is in the frequency domain nonetheless, and will let you enlarge any portion of the plot. The data points are those of the FID. You can also rotate the phase in the standard way. A phase change of 90° will reveal the imaginary part of the FID. The labels under the scale are not meaningful in this mode.
If you need to inspect the beginning of the FID, you can alternatively enlarge the window substantially.
This trick only works on the Mac.
Type this command in the console:

The advantage of this method is that the scale labels remain correct.
