Abstract
Measurement of higher members of Paschen series.—The atomic spectrum of H was investigated in the infra-red region by the photographic method. Neocyanin plates, hypersensitized by an ammonia bath, were used. A powerful discharge tube, maintained in the so-called black stage by careful adjustments, yielded under long exposures six higher members of the Paschen series, the third to the eighth inclusive. The measured wave-lengths agree with the values calculated from the Bohr theory to within the limits of experimental error.Keywords
