Chapter 15, Problem 15.3E

Interpretation Introduction

Interpretation:

The reason why the electronic transitions are considered dipole-moment allowed is to be stated.

Concept introduction:

The electronic transitions should have nonzero transition moment and should be given by the expression shown below.

$M={\displaystyle \int {\Psi }_{\text{final}}^{*}}\widehat{\mu }{\Psi }_{\text{initial}}d\tau$

Where,

• ${\Psi }_{\text{final}}^{*}$ and ${\Psi }_{\text{initial}}$ are the final and initial wavefunctions.

• $\widehat{\mu }$ is the electric dipole operator.
