What city was the birthplace of the German physicist for which Hund's coupling cases in the spectroscopy of diatomic molecules are name for?
Hund's cases In rotational-vibrational and electronic spectroscopy of diatomic molecules, Hund's coupling cases are idealized cases where specific terms appearing in the molecular Hamiltonian and involving couplings between angular momenta are assumed to dominate over all other terms. There are five cases, traditionally notated with the letters (a) through (e). Most diatomic molecules are somewhere between the idealized cases (a) and (b).
Ernst Gottfried Fischer Ernst Gottfried Fischer (17 July 1754 – 27 January 1831) was a German chemist. He was born in Hoheneiche near Saalfeld. After studying theology and mathematics at the University of Halle, he was a teacher in Berlin before becoming Professor of Physics in 1810. He translated Claude Berthollet's publication "Recherches sur les lois de l'affinitié" in 1802. He proposed a system of equivalents based on sulfuric acid equal to one hundred.
