Chapter 11, Problem 11B.11E

(a)

Interpretation Introduction

Interpretation:

Among the given molecules, those are having pure rotational spectrum has to be identified.

Concept Introduction:

Only those molecules with permanent dipole moment shows rotational spectrum.

(b)

Interpretation Introduction

Interpretation:

Among the given molecules, those are having rotational Raman spectrum has to be identified.

Concept Introduction:

For showing Raman spectrum the polarizability of the molecule must be anisotropic, that is polarizability should not be same in all directions.
