WebOptical spectrometry is the technique of measuring the intensity of absorption or emission of radiation in the ultraviolet-visible region of the spectrum. In analytical applications, these measurements are made by exciting, in various ways, transitions of electrons between outer orbitals of atoms, ions or molecular species. Optical spectrometers (often simply called "spectrometers"), in particular, show the intensity of light as a function of wavelength or of frequency. The different wavelengths of light are separated by refraction in a prism or by diffraction by a diffraction grating. Ultraviolet–visible spectroscopy is an example. These spectrometers utilize the phenomenon of optical dispersion. The light fr…
