Interpretation Introduction

Interpretation:

The vibrational frequencies of carbon tetrachloride in units of cm1 are to be calculated. The number of total vibrational frequencies of carbon tetrachloride is to be predicted.

Concept introduction:

A molecule is made up of atoms that are bonded together by covalent bonds. These bonds undergo a to and fro movement to vibrate. This vibration of the molecule contributes to the overall partition function of the system. The vibrational partition function of the polyatomic molecule is represented as,

qvib=j=13N611eθv,j/T

Where,

T represents the temperature (K).

θv,j represents the jth vibrational temperature.

N represents the number of atoms present in the molecule.
