Chapter 9, Problem 9D.6BE

Interpretation Introduction

Interpretation:

The energies of molecular orbitals in $\text{HBr}$ have to be calculated.

Concept introduction:

Molecular orbital diagrams are used for determining the bonding in molecules using a linear combination of atomic orbitals.  The number of molecular orbitals formed is equal to the number of atomic orbitals that combine.  The energy of the molecular orbital is given by the expression shown below.

  $E_{\pm }=\frac{1}{2}\left({\alpha }_{\text{A}}+{\alpha }_{\text{B}}\right)\pm \frac{1}{2}\left({\alpha }_{\text{A}}-{\alpha }_{\text{B}}\right){\left\{1+{\left(\frac{2\beta }{{\alpha }_{\text{A}}-{\alpha }_{\text{B}}}\right)}^2\right\}}^{1/2}$
