Chapter 12, Problem 12D.8P

Interpretation Introduction

Interpretation:

The EPR spectra for $\text{di}-tert-\text{butyl}$ nitroxide radical (4) at $\text{292}\text{K}$ within at low concentration, moderate concentration and at high concentration have to be drawn.

Concept introduction:

EPR stands for electronic paramagnetic resonance.  It is used to study species that contain unpaired electrons. EPR can be used to study both solids and liquids.  However, the study of the gas phase samples is difficult due to the free rotation of the molecules.  The $g-$ value represents the ease with which the applied field can generate currents through the molecule.
