Definition of Splitting and the n + 1 rule
Check what you remember
Read the wording for your board, then hide it and explain Splitting and the n + 1 rule in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Splitting follows the n + 1 rule, where n is the number of non-equivalent protons on adjacent carbon atoms, so a singlet means no neighbouring protons, a doublet one neighbour and a triplet two.
