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).
Johann Hedwig Johann Hedwig (8 December 1730 – 18 February 1799), also seen as Johannes Hedwig or Latinised as Joannis Hedwig, was a German botanist notable for his studies of mosses (for which he is sometimes called the father of bryology), in particular the observation of sexual reproduction in the cryptogams.
