ABSTRACT

Spectroscopy is often used in physical and analytical chemistry for the identification of substances through the spectrum emitted from or absorbed by them. Spectroscopy is also heavily used in astronomy and remote sensing. Most large telescopes have spectrometers, which are used either to measure the chemical composition and physical properties of astronomical objects or to measure their velocities from the Doppler Shift of their spectral lines. Visible spectroscopy is a form of Absorption spectroscopy. Absorption spectroscopy in the Visible region is to be one of the oldest and most frequently employed technique in pharmaceutical analysis for qualitative, quantitative and structural analysis of a substance in solution. The substance is analyzed by studying the spectrum produced by it due to absorption of certain wavelengths of visible light.
