The splitting expected in the proton resonance of the - C H 2 - group in triethyl phosphate, given that the coupling constants for the H - H splitting and P - H splitting happen to be identical. Concept Introduction: Phosphorus 31 P has a ± 1 2 nuclear spin. Therefore, when protons or 13 C nuclei are being observed, a nearby phosphorus atom can cause splitting.
