Question
Chapter 16, Problem 16.23E
Interpretation Introduction
Interpretation:
The total number of ESR signals that are expected from the
Concept introduction:
The full form of ESR spectroscopy is electron-spin resonance spectroscopy. The ESR spectroscopy is used to observe those materials which contain unpaired electrons. ESR spectroscopy also works like NMR spectroscopy, but, in ESR electron spin inspite of atomic nuclei spin gets excited.
