Michael Kasha

Michael Kasha (born December 6, 1920) is an American academic physical chemist and molecular spectroscopist who is one of the original founders of the Institute of Molecular Biophysics at Florida State University (FSU). He is a Distinguished University Research Professor at FSU. He is an elected member of both the National Academy of Sciences and the American Academy of Arts & Sciences, as well as the International Academy of Quantum Molecular Science. The research in his molecular spectroscopy laboratory has maintained a strong tradition of the discovery and elucidation of excitation mechanisms, with particular application to photochemical and biophysical problems. Born in Elizabeth, NJ to a family of Ukrainian immigrants, he earned his Ph.D. in chemistry from University of California at Berkeley in 1945, working with famous Nobel Prize winning scientist G.N. Lewis. His main scientific contributions include identifying triplet states as source of phosphorescence emission, formulatimg the Kasha rule on fluorescence, and work on singlet molecular oxygen.
