Chapter 14, Problem 14.84E

Interpretation Introduction

Interpretation:

Whether the combination absorptions are strong or weak in a spectrum is to be predicted. The reason for the same is to be stated.

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.
