A spectroscopic measurement is carried out with a spectrometer, of which there are many different devices for different applications available on the market. Further is became a part of other means of estimation and analysis like in chromatography, elemental analysis, and also identification tools. Thus, the emission lines will have a characteristic “fingerprint” that can be associated with a unique atom, ion, or molecule. Production and analysis of a spectrum usually require the following: (1) a source of light (or other electromagnetic radiation), (2) a disperser to separate the light into its component wavelengths, and (3) a detector to sense the presence of light after dispersion. Some of the major applications of IR spectroscopy are as follows: 1. Windows Phone. This can be performed by stepwise hydrolysis accompanied with chromatography.
