Chapter 13, Problem 13.64AP
Interpretation Introduction

(a)

Interpretation:

The reason as to why the ESR splitting pattern of methyl radical is 1:3:3:1 is to be stated.

Concept introduction:

EPR or ESR stands for electronic paramagnetic or spin resonance. It is used to study species that contain unpaired electrons. ESR 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. It is analogous to NMR spectroscopy. Here electron spin is excited instead of atomic nuclei.

Interpretation Introduction

(b)

Interpretation:

The value of operating frequency used to detect the unpaired electron magnetic resonance in magnetic field of 3400gauss and the frequency region in electromagnetic spectrum are to be stated.
