Chapter 11, Problem 11B.7BE

Interpretation Introduction

Interpretation:

The frequency and wavenumber of the $J=2\leftarrow 1$ transition in the pure rotational spectrum of ${}^{\text{12}}{\text{C}}^{16}\text{O}$ has to be calculated.  Whether the frequency increases or decreases if centrifugal distortion is considered has to be predicted.

Concept introduction:

The rotational constant is given by an expression shown below.

    $B=\frac{h}{8{\pi }^{2}Ic}$

Where,

• $I$ is the moment of inertia.
• $c$ is the speed of light.
• $h$ is the Planks constant.
