Chapter 18, Problem 18.36E

Interpretation Introduction

Interpretation:

The effect on ${\theta }_r$ of a diatomic molecule on increasing $J$ is to be stated and the reason for the answer is to be explained.

Concept introduction:

The $q_{\text{rot}}$ is given by the formula,

$q_{\text{rot}}=\frac{T}{\sigma {\theta }_r}$

The $q_{\text{rot}}$ for polyatomic molecules is given by the formula,

$q_{\text{rot}}=\frac{{\pi }^{1/2}}{\sigma }{\left(\frac{T^3}{{\theta }_{\text{r, A}}\cdot {\theta }_{\text{r, B}}\cdot {\theta }_{\text{r, C}}}\right)}^{1/2}$
