Chapter 11, Problem 11B.1DQ

Interpretation Introduction

Interpretation:

The rotational degeneracies of the various type of rigid rotator have to be stated.  Whether the loss of rigidity affects the degeneracy of rigid rotator or not has to be stated.

Concept introduction:

Rotational spectroscopy measures the electronic energy between the rotational states.  The rotational constant is inversely proportional to the moment of inertia.

The rotational constant is given by an expression shown below.

  $B=\frac{h}{8{\pi }^2{I}_{B}c}$
