Chapter 14, Problem 14.101E

Interpretation Introduction

Interpretation:

The energy level diagrams for vibrations of an ideal harmonic oscillator and an anharmonic oscillator are to drawn. The corresponding energy level diagrams are to be compared up to $\nu =25$.

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.
