Chapter 13, Problem 13B.4E

(a)

Interpretation Introduction

Interpretation:

The splitting between the methyl and aldehydic proton resonances has to be stated in a spectrometer operating at $\text{300}\text{MHz}$.

Concept Introduction:

Chemical shifts:

The chemical shifts $\left(\text{δ}\right)$ is given by,

$\begin{array}{l}\text{δ}\text{=}\frac{\text{ν}\text{-}{\text{ν}}_{\text{0}}}{{\text{ν}}_{\text{0}}}\text{×}{\text{10}}^{\text{6}}\\ \text{where,}\\ \text{δ}\text{-}\text{chemical}\text{shift}\\ \text{ν}\text{-}\text{resonance}\text{frequency}\text{of}\text{the}\text{sample}\\ {\text{ν}}_{\text{0}}\text{-}\text{resonance}\text{frequency}\text{of}\text{the}\text{standard}\end{array}$
