Chapter 11, Problem 11D.4AE

Interpretation Introduction

Interpretation:

An expression for the vibrational term for the ground vibrational state of ${\text{H}}_{\text{2}}\text{O}$ in term of wave numbers of the normal modes has to be stated.

Concept introduction:

The different types of vibrational motions in a molecule are described by normal modes of vibrations.  The total number of vibrational degrees of freedom for nonlinear molecule is represented by $3N-6$.  The total number of vibrational degrees of freedom for linear molecule is represented by $3N-5$.
