Interpretation Introduction

(a)

Interpretation:

The depolarization ratio at wave number 760cm1 and type of the Raman lines are to be stated.

Concept introduction:

The scattering theory state that the maximum value for the depolarization ratio is 0.85.

If the value of depolarization ratio is near by the maximum value of the depolarization ratio than Raman lines are depolarized. If the value of depolarization ratio is very far from the maximum value of the depolarization ratio than Raman lines are polarized. Therefore, the maximum value of the depolarization ratio indicates the depolarized Raman lines and the minimal value of the depolarization ratio indicate the polarized Raman lines.

(b)

Interpretation:

The depolarization ratio at wave number 660cm1 and type of the Raman lines are to be stated.

Concept introduction:

The scattering theory state that the maximum value for the depolarization ratio is 0.85.

If the value of depolarization ratio is near by the maximum value of the depolarization ratio than Raman lines are depolarized. If the value of depolarization ratio is very far from the maximum value of the depolarization ratio than Raman lines are polarized. Therefore, the maximum value of the depolarization ratio indicates the depolarized Raman lines and the minimal value of the depolarization ratio indicate the polarized Raman lines.

Interpretation Introduction

(c)

Interpretation:

The depolarization ratio at wave number 357cm1 and type of the Raman lines are to be stated.

Concept introduction:

The scattering theory state that the maximum value for the depolarization ratio is 0.85.

If the value of depolarization ratio is near by the maximum value of the depolarization ratio than Raman lines are depolarized. If the value of depolarization ratio is very far from the maximum value of the depolarization ratio than Raman lines are polarized. Therefore, the maximum value of the depolarization ratio indicates the depolarized Raman lines and the minimal value of the depolarization ratio indicate the polarized Raman lines.

Interpretation Introduction

(d)

Interpretation:

The depolarization ratio at wave number 258cm1 and type of the Raman lines are to be stated.

Concept introduction:

The scattering theory state that the maximum value for the depolarization ratio is 0.85.

If the value of depolarization ratio is near by the maximum value of the depolarization ratio than Raman lines are depolarized. If the value of depolarization ratio is very far from the maximum value of the depolarization ratio than Raman lines are polarized. Therefore, the maximum value of the depolarization ratio indicates the depolarized Raman lines and the minimal value of the depolarization ratio indicate the polarized Raman lines.
