Chapter 25, Problem 25.8P

Interpretation Introduction

Interpretation:

The splitting expected in the proton resonance of the $-\mathrm{C}{\mathrm{H}}_2-$ group in triethyl phosphate, given that the coupling constants for the $\mathrm{H}-\mathrm{H}$ splitting and $\mathrm{P}-\mathrm{H}$ splitting happen to be identical.

Concept Introduction:

Phosphorus $\left({\mathrm{ }}^{31}\mathrm{P}\right)$ has a $\pm \frac{1}{2}$ nuclear spin. Therefore, when protons or $\left({\mathrm{ }}^{13}\mathrm{C}\right)$ nuclei are being observed, a nearby phosphorus atom can cause splitting.
