spin spin coupling
The source of signal splitting is a phenomenon called spin-spin coupling, a term that describes the magnetic interactions between neighboring, non-equivalent NMR-active nuclei. In our 1,1,2 trichloromethane example, the Ha and Hb protons are spin-coupled,Introduction to Spin-Spin Coupling in H-NMR. Recall that protons have a magnetic field associated with them (since they have a nuclear spin), and when they are placed in a magnetic field approximately half of the protons become aligned with the field and
