Chapter 16, Problem 16.2QAP

Interpretation Introduction

(a)

Interpretation:

The force constant for $\text{HCl}$ bond should be determined.

Concept introduction:

The force constant is defined as the restoring force divide by unit distance by which the bond is stretched out. The force constant is used for the analysis and characteristics of the molecules.

Interpretation Introduction

(b)

Interpretation:

The wavenumber of the absorption band for $\text{DCl}$ should be determined.

Concept introduction:

The wavenumber is defined as the wavelength per unit distance. The wavenumber is generally expressed in ${\text{cm}}^{-1}$.
