Proton Spectrum
H171804E_14_001 61 / 86
8.4 Integration
To quantitatively analyze an observed proton signal, the integrated intensity of the peaks is
compared within each other. It is common to integrate a proton spectrum to account for the
number of protons in the analyzed molecule.
To  get  more  precise  quantitative  integration  results,  please  refer  to  the  Quantitative  NMR
manual.
• Expand the spectrum to include all peaks.
• On the menu, click Analyse | Integrate.
This  enters  the  manual  Integration  mode.  The  Dataset  tabs  bar  is  replaced  by  the
Integration Tool bar.
• Select the Define new region using cursor button. 
• Set the cursor line to the left of the first peak to be integrated. Click the left mouse button
and drag the cursor line to the right of the peak and then release the mouse button.
