In 1913, Stark observed a splitting of the lines of the Balmer series of hydrogen (8.2) in an electric field. He was studying the light emission of H atoms in the field of a condenser (Figs. 15.1, 2). Since then, frequency shifts in optical spectra in the presence of eletric fields have been generally called the Stark effect.
