Chapter 14, Problem 14.70E

Interpretation Introduction

Interpretation:

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

Concept introduction:

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

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

Where,

• $D_0$ is 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.
