Chapter 12, Problem 12D.4P

Interpretation Introduction

Interpretation:

The form of the EPR spectrum of $\text{1,4-dinitrobenzene}$ radical anion has to be stated.

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 $g\text{-}$ value represents the ease with which the applied field can generate currents through the molecule.
