11. Absorption spectroscopy is useful in chemical analysis because of its specificity and its quantitative nature.12. The technique is referred to as gas in scattering media absorption spectroscopy ( GASMAS ). 13. Compared to atomic absorption spectroscopy , ICP-MS has greater speed, precision, and sensitivity. 14. In atomic absorption spectroscopy , light of a predetermined wavelength is passed through a collection of atoms. 15. Transient-absorption spectroscopy , also known as flash spectroscopy, is an extension of spectrophotometric techniques. 16. For example, Atomic absorption spectroscopy is used to identify alloys of gold, bronze and copper. 17. Absorption spectroscopy is employed as an Infrared and ultraviolet-visible spectroscopy are particularly common in analytical applications.18. Absorption spectroscopy is also employed in studies of molecular and atomic physics, astronomical spectroscopy and remote sensing.19. A common and simple method for determining whether a band gap is direct or indirect uses absorption spectroscopy . 20. A few examples of absorption are ultraviolet visible spectroscopy, infrared spectroscopy, and X-ray absorption spectroscopy .
