    Notes: [Auszug] The lower dispersion spectra show unusually high relative intensities of the first negative N2+ bands for higher vibrational levels; this effect was first observed by Stormer and explained by Bates2 as due to an abnormal distribution of the populations of the vibrational levels of N2+ resulting ...

    Infra-red Spectrum of the Night Sky near 10000 A. (1955)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] The measured wave-lengths of the stronger features are recorded in Table 1. Almost all the features can be attributed to lines and branches of the (5,2), (4,1), (3,0), (9,5) and (8,4) OH rotation-vibration bands. The predicted wave-lengths (in air) for the lines of the (5,2), (4,1) and (3,0) bands ...

    Ca II Emission Lines in the Twilight Spectrum (1956)
    [s.l.] : Nature Publishing Group
    Nature 178 (1956), S. 276-277

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The wave-lengths of the H and K lines of ionized calcium are 3933.7 A. and 3968.5 A. Comparison of the measured wave-lengths with the M.I.T. Wavelength Tables 1 showed that no other element besides Ca II could give rise to both emission lines. A measured intensity ratio of 2.1 ± 0.5 is ...

    Notes: [Auszug] Twilight spectra covering the region 6000-7000 A. have been obtained at Saskatoon regularly since January 1959. An //0-8 auroral grating spectro-graph7 was used to photograph the spectrum on Kodak 103 a-F plates. During the exposures the spectrograph was guided according to an exposure programme ...
