Spectroscopic Measurements as Scientific Tool

Abstract

This paper is an attempt to introduce the spectroscopic measurement techniques in simple form. It covers the meaning of 'Spectroscopy' in general and infrared, visible and ultra-violet spectroscopy in particular. The instruments and techniques involved to observe and analyse different spectrum are highlighted under emission spectroscopy and absorption spectroscopy. Finally, the application of spectrographic methods in various fields of sciences like chemistry, physics, astronomy, biology and medicine, food science, metallurgy and forensic science are discussed in brief without going into any technical complexities.
