Chapter 13, Problem 13.2P
Interpretation Introduction

(a)

Interpretation:

The reduction in the shielding of the protons a respective to the protons of TMS in terms of gauss is to be stated.

Concept introduction:

Many nuclei and electrons have spin. Due to this spin magnetic moment arises. The energy of this magnetic moment depends on the orientation of the applied magnetic field. In NMR spectroscopy, every nucleus has a spin. There is an angular momentum related to the spin. The difference between its resonance frequency and that of the reference standard is known as the chemical shift of a nucleus. Tetramethylsilane (TMS) is taken as reference.
