spectroscopy

Also contains definition of: spectrometry

The study of physical systems<ref>Representative parts of the system (for example, serum) may be treated (for example, diluted) before measurement. In analytical chemistry, the instrumentation or parts of it may also be considered as systems</ref> by the electromagnetic radiation with which they interact or that they produce. Spectrometry is the measurement of such radiations as a means of obtaining information about the systems and their components. In certain types of optical spectroscopy, the radiation originates from an external source and is modified by the system, whereas in other types, the radiation originates within the system itself.

In this document,the word 'component' is also used to designate a neutral atom whose concentration in a physicochemical plasma is proportional to the concentration of the original component in the material being analysed.".
