An analytic technique concerned with the measurement of the interaction (usually the absorption or the emission) of radiant energy with matter, with the instruments necessary to make such measurements, and with the interpretation of the interaction both at the fundamental level and for practical analysis. In the various spectroscopic techniques, the range of energies studied spans the entire electromagnetic spectrum (Fig. 1). Mass spectroscopy is not concerned with the interaction of light with matter, but was so named because the appearance of the data resembles that of the spectroscopic data as just defined.
