How to Bin a Spectrum
Process the spectrum as usual and reference it against TMS or another signal.
Choose Process > Make Bins. For each frequency axis (if the spectrum has more than 1 dimension) specify:
The lowest frequency, in ppm, of the region of interest.
The highest frequency.
The size of each bin, in ppm.
Normally you set the last parameter (edge corr.) to zero, which means it's not used.
This parameter performs an additional baseline correction. Considering that you have already corrected the baseline with the more refined functions of iNMR, and that you can probably do an equivalent correction with a statistical package, this additional treatment should rarely be necessary. In practice, if you specify a value n for edge corr., iNMR calculates the average value of the first n and the last n bins and subtracts it from all the bins.
