Interaction of matter with a radiative energy as function of wavelength or frequency
Some common spectroscopic methods include:
First of all, we understand the term Ultraviolet radiation, a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays.
Visible radiation, on the other hand, refers to the portion of the electromagnetic spectrum that can be seen by the human eye, with wavelengths ranging from approximately 400 to 700 nanometers.
Ultraviolet-visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. Ultraviolet-visible (UV-VIS) spectroscopy is an analytical method that can measure the analyte quantity depending on the amount of light received by the analyte.
Infrared (IR) spectroscopy measures the absorption or transmission of infrared light, which corresponds to molecular vibrations and rotations. It provides information about the functional groups and chemical bonds present in a compound, aiding in the identification and characterization of organic and inorganic molecules.
