Book excerpt: Excerpt from Wave Lengths in the Red and Infra-Red Spectra of Iron, Cobalt and Nickel Arcs The are spectra of iron, cobalt, and nickel were photographed in the red and infra-red regions on plates stained with pinacyanol and dicyanin. A large concave grating was used, and exposures up to 10 hours duration registered many. Lines with wave lengths greater than 10 000 A, or 1 micron. In the arc spectrum of iron, 298 lines were measured between the wave-length limits 67 50 A and 10 689 A; 606 lines were measured between 5 503 A and 11 623 A in the arc spectrum of cobalt and 290 lines between 5504 A and 10 843 A in the arc spectrum of nickel. As far as possible, impurities were. Eliminated and lines assigned to their proper' element. Four lines due to oxygen were found in these arc spectra and are included in the wave-length tables. These results demonstrate that an invisible long-wave interval as large as the entire visible spectrum is accessible to photography with dicyanin-stained plates. The incompleteness of spectroscopic data for these longer light waves invites extensive application of this method of spectrum photography.
