SPECTROSCOPY
Atoms and molecules interact with electromagnetic radiation (EMR) in a wide variety of ways.
Atoms and molecules may absorb and/or emit EMR.
Absorption of EMR stimulates different types of motion in atoms and/or molecules.
The patterns of absorption or emission are called ‘spectra’.
The field of spectroscopy is concerned with the interpretation of spectra in terms of atomic and molecular structure (and environment).
