Chapter 16, Problem 16.24P

Interpretation Introduction

Interpretation:

Which signal or signals represent protons coupled with the protons with $\text{δ = 4}\text{.1 ppm}$ in the given ${}^{\text{1}}\text{H}$ NMR spectrum is to be determined.

Concept introduction:

In ${}^{\text{1}}\text{H}$ NMR, the coupling of the spin states of one nucleus with the spin states of adjacent or neighboring nuclei is called spin-spin coupling. The coupling constant is the frequency difference between peaks of a split signal. The coupling constant for the signals of the protons that couple with each other is the same.
