Information is encoded in two broad ways: as electrical information and as information in other, non-electrical forms. In this section we will consider how we can measure electrical signals.

Because these techniques use optical materials to disperse and focus the radiation, they often are identified as optical spectroscopies. For convenience we will use the simpler term spectroscopy in place of optical spectroscopy; however, you should understand that we are considering only a limited part of a much broader area of analytical techniques.

It covers the principles of spectroscopy using ultraviolet, visible, and infrared radiation. The chapter explains the wave and particle nature of electromagnetic radiation, highlighting its fundamental properties and explaining how matter absorbs or emits photons.
