Much of the radiation passes through the sample without a loss in intensity. At selected wavelengths, however, the radiation’s intensity is attenuated. This process of attenuation is called absorption.

The historical development of AES is highlighted, with applications evolving from flame and spark techniques to plasma sources. AES is suitable for multielemental analysis and involves equipment like atomic emission spectrometers using flames or plasmas.

Atomic emission occurs when a valence electron in a higher energy atomic orbital returns to a lower energy atomic orbital. The emission consists of a series of discrete lines at wavelengths corresponding to the difference in energy between two atomic orbitals.
