Chapter 10, Problem 10C.1BE

Interpretation Introduction

Interpretation:

Whether the integral ${\displaystyle \int {\text{p}}_{\text{x}}z{\text{p}}_{\text{z}}\text{d}\tau }$ is zero or not has to be stated using the symmetry properties of a molecule belonging to $D_{3h}$ point group.

Concept introduction:

A symmetry operation is defined as an action on an object to reproduce an arrangement using symmetry argument.  The spatial arrangement of the object remains identical after a symmetry operation.  The point of reference through which a symmetry operation takes place is termed as a symmetry element.
