Chapter 11, Problem 11B.14AE

Interpretation Introduction

Interpretation:

The ratio of the weights of populations due to the effect of nuclear statistics for ${}^{35}{\text{Cl}}_2$ has to be calculated.

Concept introduction:

Nuclear statistics is the selective existence of some rotational states in rotational spectra over others.  Nuclear statistics must be taken into account when rotation changes the equivalent nuclei.  Several different relative nuclear spin orientations are consistent with even values of the rotational quantum number and a different number of spin orientations are consistent with odd values of rotational quantum number.
