Chapter 20, Problem 20.36QP

Interpretation Introduction

Interpretation:

The ozone molecule is a greenhouse gas or not has to be identified.  Also the molecular vibrations of ozone molecule has to be sketched.

Concept Introduction:

Greenhouse gas:

Earth receives solar energy from sun, which is in range of wavelength between $\text{100 and 5000nm}$ but most radiations are in $\text{400-700nm}$(visible region).  On the other hand, earth surface emits radiation of wavelength greater than $\text{4000nm}$(IR region).  These outgoing IR radiations are only absorbed by IR active compounds present in stratosphere.  Compounds having dipole moment or its vibrational motion produce dipole moment are IR active compounds.  These IR active compounds are called as greenhouse gas.
