Answer 2

In the ESR spectrum, the types of interaction involved are B. nucleus -electron interaction.

• ESR is electron soon resonance spectroscopy where we deal with the interaction occurring between the nucleus and electron.
• The principle of ESR is that when an unpaired electron is subjected to a strong magnetic field then it absorbs microwave. so, it absorbs energy with a wavelength in the microwave region.
• ESR is not shown by paramagnetic substances because there is no unpaired electron for microwave absorption.
• In ESR spectroscopy detector used is a rectifier which is consist of silicon and tungsten.
