[4] In 1913 Hahn published her first paper, entitled Saturated δ-Ketonic Esters and their Derivatives,[6] confirming the ring structure of hydantoins utilizing ultraviolet spectrophotometry techniques developed by her colleague Emma Perry Carr.
These books included A Dictionary of Chemical Solubilities, Inorganic (1921), The Catalytic Oxidation of Organic Compounds in the Vapor Phase (1932) and Pyrimidines: Their Amino and Aminoxy Derivatives (1933).
[5] Outside of academia, Hahn showed interest in industrial chemistry and conducted research on coal tar products in the private sector.
