Chapter 14, Problem 14.33E

Interpretation Introduction

Interpretation:

The most populated rotational level at $350\text{K}$ for ${\text{O}}_{\text{2}}$ is to be calculated.

Concept introduction:

An electronic state of energy has its own vibrational states. The energy between the electronic states is large followed by vibrational states and then rotational states. During an electronic transition, electron from ground state moves straight to the excited state keeping the internuclear distance constant. This is known as the Franck-Condon principle.
