Chapter 15, Problem 15.38E

Interpretation Introduction

Interpretation:

The set of energy levels having largest Franck-Condon overlap integral is to be stated. The answer is to be explained.

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.
