Interpretation:
The spin and number of equivalent nuclei required to produce the given ESR spectrum are to be stated.
Concept introduction:
Electron spin resonance is the method to study the materials with an unpaired electron. An unpaired electron absorbs the microwave radiation under the strong magnetic field. The difference between two energy levels is calculated by the formula shown below.
