Spectroscopic analysis is the use of electromagnetic wavelength observation to determine chemical identities, structures, and reaction intermediates.
Explanation:
There are many, many online references about different spectroscopic methods and uses, so I will only note the basic principles, as requested.
A "spectrum" is any range of electromagnetic wavelengths - not only the visible ones. Common analytical ranges include near-Infrared, Infrared and Ultraviolet regions as well as visible light.
Light emitted or absorbed by elements and compounds under different conditions is constant and can be related to the specific element, compound, or even reactions.
We use this property to identify chemical materials.
