Chapter 9, Problem 9B.4BE

Interpretation Introduction

Interpretation:

The $\text{g}$ and $\text{u}$ character of bonding and antibonding $\text{δ}$ orbitals formed by face-to-face overlap of $\text{d}$ orbitals has to be predicted.

Concept introduction:

A molecular orbital of homo-nuclear diatomic molecule is labeled as gerade and ungerade.  These terms are used to represent the inversion symmetry.  The gerade and ungerade words derived from the German language.  Gerade means even and ungerade means odd.  Therefore, gerade symmetry means even symmetry while ungerade symmetry means odd symmetry.
