Interpretation Introduction

Interpretation:

An explanation corresponding to the fact that the first excited state of ${\text{H}}_{\text{2}}$ is represented by three very closely spaced lines in the spectrum is to be stated.

Concept introduction:

When an atom or a molecule makes electronic transition from a high energy state to a lower energy state, the spectrum of different frequencies of electromagnetic radiations is obtained known as emission spectrum.
