'''Spectroscopy''' covers a wide range of measurement techniques, the core concept of which being that they determine the [[amplitude]] of individual [[frequency|frequencies]] of interest in the spectrum of a complex signal. That signal is most often in the [[electromagnetic spectrum]], but can also be acoustic.
'''Spectrometry''' describes quantitative [[spectroscopy]] — the analysis of absolute and/or relative contributions of frequency components to the spectrum of a given sample or object.      


The signal of interest may be emitted by the subject, reflected by it, or selectively absorbed by it. Spectrometric information from multiple views of a subject may be used to construct images.
As a technique of chemical analysis, it can measure either the emission or absorption of substances at various frequencies.
