Chapter 11, Problem 11F.6P

(a)

Interpretation Introduction

Interpretation:

The conclusions that can be drawn from the nature of the orbital from which the electron of ${\text{H}}_{\text{2}}\text{O}$ is ejected has to be stated.

Concept introduction:

Spectroscopy method is used to identify the structure of the substance.  It is based on the interactions between matter and electromagnetic radiations.  The complex vibrations exhibited by the polyatomic molecule are known as normal modes of vibrations.  The vibrational modes of a molecule are IR or Raman active.  The total number of vibrational degrees of freedom for the nonlinear molecule is represented by $3N-6$.

(b)

Interpretation Introduction

Interpretation:

The conclusions that can be drawn about the characteristics of the orbital occupied by the photoelectron of ${\text{H}}_{\text{2}}\text{O}$ has to be stated.

Concept introduction:

As mentioned in concept introduction in part (a).
