Chapter 14, Problem 14.85E

Interpretation Introduction

Interpretation:

The reason as to why it is possible to identify group frequency regions for overtone transitions and hot bands but not for combination bands is to be stated.

Concept introduction:

An electronic state of energy has its own vibrational states. The energy difference 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.
