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).
Franz Hein Franz Hein was born in Grötzingen (Baden), Germany. His high school years were spent in Leipzig, as well as, his college years at the University of Leipzig. He completed his Ph.D. in 1917 on optical studies of bismuth and triphenylmethane derivatives. Hein made "Assistant" at the University and in 1920 "Oberassistent". He continued working on his "Habilitation" becoming a professor in 1923. With the completion of his "Habilitation", Hein went to work on organometallic system electrochemistry.
