Chapter 10, Problem 10C.7BE

Interpretation Introduction

Interpretation:

The irreducible representations spanned by the set of basis functions that span a reducible representation of the group $D_{\text{2}}$ have to be stated.

Concept Introduction:

The systematic discussion of symmetry is known as group theory.  The table showing all the characters of the operations of a group is termed as character tables.  The character of an operation in a particular matrix is the sum of the diagonal elements of the representative of that operation.
