An instrument used to determine the relative intensity of various wavelengths in a spectrum of light. spec′tro·pho′to·met′ric (-fō′tə-mĕt′rĭk) adj.spec′tro·pho·tom′e·try n. Translations spettrofotometria Spectrophotometry spectrophotometry [¦spek·trō·fə′täm·ə·trē] (analytical chemistry) A method of chemical analysis based on the absorption or attenuation by matter of electromagnetic radiation of a specified wavelength or frequency. The radiation interacts with specific features of the molecular species being determined, such as the vibrational or rotational motions of the chemical bonds. The radiation can also interact with specific atoms or the whole molecule, for example, by causing the molecule to change its electronic energy state. Spectrophotometry a branch of measurement technology that draws on spectrometry, photometry, and metrology in developing methods and instruments for the quantitative measurement of spectral absorptance, reflectance, emissivity, and luminance as quantities characterizing media, coatings, surfaces, and radiators. spectrophotometry spectrophotometry [spek″tro-fo-tom´ĕ-tre] the use of the spectrophotometer. spec·tro·pho·tom·e·try (spek'trō-fō-tom'ĕ-trē), Analysis by means of a spectrophotometer. spectrophotometry Lab medicine The use of a spectrophotometer to evaluate a fluid for a molecule of interest, based on the molecule's ability to alter the transmission of light at specific wavelengths. See Fluorescence spectrophotometry. spec·tro·pho·tom·e·try (spek'trō-fŏ-tom'ĕ-trē) Analysis by means of a spectrophotometer. ThesaurusSeespectrophotometer
