Chapter 3, Problem 22P

Interpretation Introduction

Interpretation:

The number of degrees of vibrational freedom for each of the following: (a) ${\text{SO}}_{\text{2}}$ (b) ${\text{SiH}}_{\text{4}}$ (c) $\text{HCN}$ (d) ${\text{H}}_{\text{2}}\text{O}$ (e) ${\text{BF}}_{\text{3}}$ is to be determined.

Concept Introduction:

Raman and infrared (IR) spectroscopies are branches of vibrational spectroscopy.

Vibrational spectroscopy is concerned with the observation and determination of number of the degrees of vibrational freedom.

The degrees of vibrational freedom depends on the number of atoms in molecule and shape of the molecule.
