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.

Book excerpt: Excerpt from Wave-Length Measurements in Arc Spectra Photographed in the Yellow, Red, and Infra-Red For several years the Bureau of Standards has been conducting grating measurements in red and infra-red arc spectra by the aid of specially sensitized photographic plates to improve the data in this region and to find some element which would furnish lines suitable for wave-length standards in this region. To the 25 elements already measured the following are here added: Silver, aluminum, gold, bismuth, cadmium, mercury, lead, antimony, tin, and zinc.

This book was released on 2016-09-30 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Absorption Spectra of Iron, Cobalt, and Nickel The structure of the nickel arc spectrum has been discussed by Walters (34) and by Bechert and Sommer the term combina tions in Table 5 being taken in large part from these papers but with a revision of the notation. The are spectrum of nickel has three terms which account for all the arc lines identified in absorption; they are 3f, 3d, and 1d in the order of increasing energy, but the first two completely overlap and all three have a range of only slightly more than one-third of a volt in the energy scale. The complete set of low terms is presented in table 6. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2018-03-21 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Infra-Red Spectra of Neon Argon and Krypton Neutral atoms of the noble gases are characterized by spectra of exceptional utility and rare beauty. Geissler tubes containing these gases at low pressure when excited by moderate electrical discharges, emit spectral lines of high homogeneity which have been demonstrated to be reproducible within 1 part in These lines are favor ably regarded as standards of wavelength, and are extensively used in spectroscopy and metrology. It is not unlikely that one of these lines may ultimately be chosen as the most practical and permanent primary standard of length, especially if an even-numbered isotope can be segregated so that the strongest lines will be free from hyperfine structure. From a theoretical viewpoint the first. Spectra of the noble gases are of special interest because they arise in each case from a; closed shell configuration of electrons, and unlike other complex spectra they are found to consist of extended series of relatively simple types terms) and low multiplicities (singlets and triplets). Evi dence of a gradual transition from sl to jj electron coupling as the atomic complexity increases adds interest to a comparison of the spectral structures of all the noble gases.
