3. Integration (in case of H-NMR only): area under NMR signal that is proportional
to number of protons in the set.

4. Spin-spin splitting (multiplicity) of signals (in case of H-NMR only) = the number
of lines forming single NMR peak.

▪ Peaks are often split into multiple lines due to magnetic interactions between
nonequivalent protons on adjacent carbons.

▪ The signal of one H splits into n + 1 peaks, where n = number of H on neighboring
carbons.

▪ Splitting patterns are: singlet (s), doublet (d), triplet (t), quartet (q) & it could be

called multiplet (m) in case of splitting higher that quartet.
