TYPES OF SPECTROSCOPY

Spectroscopy is the analysis of the interaction between matter and any portion of the electromagnetic spectrum. Traditionally, spectroscopy involved the visible spectrum of light but X-Ray, gamma and UV spectroscopy also are valuable. Analytical techniques spectroscopy may involve any interaction between light and matter including absorption, emission, scattering, etc. Data obtained from spectroscopy is usually presented as a spectrum that is a plot of the factors being measured as a function of either frequency or wavelength. Principle : Spectroscopy is the measurement and interpretation of electromagnetic radiation which is absorbed or emitted by atoms of a sample. This absorption or emission happens when the atoms of the sample move from one energy state to another in presence of light. Every sample has molecules consisting of some functional groups by which they may incur color or some nature to absorb light of specific wavelength. This wavelength at which sample
