PROTON COUNTING
The areas under the NMR signals may be integrated numerically for 1H signals.
• Integration gives a line over the peak and a number, the latter gives the relative number of Hs in that signal to the next signal.
10
30
eg. CH3CHCl2
The ratio is 10 : 30
indicating that
there is 1H under the
quartet signal for
every 3Hs under the
doublet signal.
