Chapter 18, Problem 18.12E

Interpretation Introduction

Interpretation:

The value of $D_{\text{e}}$ for ${\text{H}}_{\text{2}}\text{O}$ is to be predicted.

Concept introduction:

The point at which the bond between the two atoms become nonexistent thus the molecule exits as two separated atoms known as dissociation limit. The relation between $D_0$ and $D_{\text{e}}$ is given by the formula,

$D_0=D_{\text{e}}-\frac{1}{2}hv$

Where,

• $D_0$ represents dissociation energy.

• $h$ is the Plank’s constant.

• $v$ is vibrational frequency.

• $D_{\text{e}}$ is the minimum potential energy of ground electronic state with respect to the zero point.
