Spectroscopy are optical methods for analysis of gaseous compounds. There are many techniques for gas analysis that involve observations of the electromagnetic radiation spectrum. The relevant part of the spectrum consists of: X-rays, ultraviolet, visible light and infrared. The ultraviolet, visible and IR regions are particularly relevant to gaseous air pollutant analysis, whereas X-ray methods are more relevant to particulate-phase pollutants and will not be discussed here.
