What Spin–spin splitting means in Chemistry A-Level, as defined for OCR.
Definition of Spin–spin splitting
Check what you remember
Read the wording for your board, then hide it and explain Spin–spin splitting in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The splitting of a proton's signal in high-resolution ¹H NMR caused by the magnetic states of non-equivalent protons on adjacent carbon atoms.
