Chapter 11, Problem 11B.1E

Interpretation Introduction

Interpretation:

Rotational quantum number has to be determined.

Concept Introduction:

The total rotational kinetic energy of a linear rotor is given by,

  $\begin{array}{c}\text{E}\text{= }\frac{\hslash }{\text{4πI}}\text{J}\left(\text{J+1}\right)\\ \\ \text{where,}\\ \text{I = Rotational constant}\\ \text{J}\text{= Rotational quantum number }\end{array}$

Moment of inertia of diatomic molecules is given by,

  $\text{Moment of inertia, I = }\mu {\text{R}}^2$
