    Notes: [Auszug] DEHYDRATED crystals of barium azide decompose at a measurable rate above 100° C. giving nitrogen as a gaseous product. There is an induction period very similar to that observed with mercury fulminate and the reaction spreads from centres of metallic barium formed on the surface and in the ...

    Notes: [Auszug] I HAVE read with considerable interest the suggestion of Dr. H. S. Allen in NATURE for March 18 that the Langmuir atom could be applied with advantage to the study of organic compounds. Dr. Allen is, however, doubtful if the “cubical atom” of Langmuir wiil explain the existence of isomerides of ...

    Notes: [Auszug] THE application of the Bohr theory to organic chemistry suggests a possible explanation of the hitherto unexplained isomerism of certain organic compounds. The electrons rotating in pairs around the four carbon valencies may possess either clockwise or anti-clockwise rotation with respect to ...

    Notes: [Auszug] PROF. H. S. TAYLOR has pointed out to us that it is not clear from our paper on the heats of adsorption of oxygen on charcoal (Blench and Garner, J.C.S.,1924, 125, 1288) that the values were expressed in kgm.-cal. and also that we had not discussed the bearing of these results on the mechanism ...

    Polar and Non-Polar Valency in Organic Compounds (1922)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THERE is an increasing tendency on the part of organic chemists to apply the Berzelius dualistic theory, in a modified form, to organic compounds. In many theories of valency, individual groups are considered to be more or less electropositive or electronegative, and it is possible to arrange ...
