    Effect of Pressure on High Terms of Alkaline Spectra (1934)
    [s.l.] : Nature Publishing Group
    Nature 133 (1934), S. 141-141 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IN the alkaline spectra, very long absorption series have been observed. Wood and Fortrat have detected 56 terms of the Na, 3S–nP series. One might expect that the high terms of the series would be destroyed by adding a foreign gas, as the excited states of high quantum number, have such a ...

    Hexuronic Acid as the Antiscorbutic Factor (1932)
    [s.l.] : Nature Publishing Group
    Nature 130 (1932), S. 888-888 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] A CHARACTERISTIC property of Prof. Szent-Györgyi's hexuronic acid is its behaviour towards iodine. Two atoms of iodine are taken up in aqueous solution (neutral or acid) with formation of two molecules of hydrogen iodide. We find that this is due to oxidation at a double bond. The intervention ...
