Edited sentence: Algorithms used in Spectroscopy.Applied spectroscopy.Fourier transform spectroscopy.In this region of the electromagnetic spectrum, molecules undergo electronic transitions.Infrared spectroscopy is another common spectroscopic technique, usually used to obtain free information about the structure of compounds.Near infrared spectroscopy.Rotational spectroscopy.The absorption in the visible ranges directly affects the color of the chemicals involved.This means it uses light in the visible and adjacent (near ultraviolet (UV) and near infrared (NIR)) ranges.This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.Ultraviolet-visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) involves the spectroscopy of photons in the UV-visible region.Vibrational spectroscopy.cs:Ultrafialovo-viditelná spektroskopie.de:UV/VIS-Spektroskopie.es:Espectroscopia ultravioleta-visible.fr:Spectroscopie ultraviolet-visible.ja:紫外・可視・近赤外分光法.nl:UV/VIS-spectroscopie.nn:UV/VIS-spektroskopi.pl:Spektroskopia UV-VIS.pt:Espectroscopia UV/visível.ru:Оптическая спектроскопия.zh:紫外光谱
