Module 3 : Molecular physics and molecular structure
Lecture 29 : The rotational-vibrational spectra
 
  Objectives
  • In this lecture, we will find out the rotational-vibrational spectrum of a diatomic molecule.
  • The analysis of the rotational spectrum will be carried out using non rigid rotor approximation.
  • The rotational structure of the vibrational band will be understood.
  • The temperature effect of the rotational-vibrational spectrum will also be discussed.
