The Basics of UV-Vis Spectroscopy
www.agilent.comSpectroscopy allows the study of how matter interacts with or emits electromagnetic radiation. There are different types of spectroscopy, depending on the wavelength range that is being measured. UV-Vis spectroscopy uses the ultraviolet and visible regions of the electromagnetic spectrum. Infrared spectroscopy uses the lower energy infrared part of

Chapter 1: UV-Visible & Fluorescence Spectroscopy
www.orgchemboulder.com(often abbreviated as UV-Vis) and fluorescence emission spectroscopy. These two methods are measured over the same range of wavelengths, but are caused by two different phenomena. In both cases, the wavelengths used are the near-ultraviolet range (200 to 400 nm) and the visible range (400 to 750 nm).

Light visible to the human eye occupies only a small portion of the electromagnetic spectrum, namely from about 350 to 750 nanometers, or from violet to red.
Spectroscopy: Principles, Theory, Techniques and Applications
mazams.weebly.comVisible absorption spectroscopy is often combined with UV absorption spectroscopy in UV/Vis spectroscopy. Although this form may be uncommon as the human eye is a similar indicator, it still proves useful when distinguishing colours. Ultraviolet All atoms absorb in the Ultraviolet (UV) region because these photons are energetic enough
