INTRODUCTION
Spectroscopy is the measurement and interpretation of Electromagnetic radiation (EMR) absorbed or emitted when the molecules or atoms or ions of a sample move from one energy state to another energy state. This change may be ground state to exited state or vice-versa. EMR is made up of discrete particles called photons. EMR has got both wave characteristic as well as particle characteristics. This means that it can travel in vacuum also.
