Chapter 12, Problem 12B.2ST

Interpretation Introduction

Interpretation:

An expression for ${\sigma }_{\text{d}}$ for a hydrogenic atom with nuclear charge $Z$ has to be derived.

Concept introduction:

The NMR frequency of a given molecule depends upon its nuclear environment.  The chemical shift of a nucleus is the difference between its resonance frequency and that of a reference standard.  The standard for ${}^1\text{H}$ and ${}^{13}\text{C}$ is trimethylsilane, known as TMS.
