Miguel Antonio Catalán Sañudo (1894–1957) was a Spanish spectroscopist. Born in Zaragoza, he obtained his degree in chemistry from the University of Zaragoza and received his doctorate in Madrid in 1917 for his thesis about spectrochemistry. In 1920, he began work as a researcher at Imperial College London. Examining the spectrum of the arc of manganese, he determined that the optical spectra of complex atoms consisted of groups of lines –which he called "multipletes"- between which existed certain characteristic regularities. Catalán demonstrated that study of the multipletes led to further understanding of the states of energy of atomic electrons.
