    Notes: [Auszug] THAT a quantum of radiation can be absorbed in part by an atomic system, and the remaining part scattered by it giving rise to a radiation of increased wave-length, has been demonstrated by recent work on the scattering of light in material media. In his address on “A New Radiation” (Ind. Jour. ...

    Notes: [Auszug] THE appearance in the spectrum of monochromatic light diffused by fluids, of new lines of modified frequency (Ind. Jour. Phys., vol. 2, pp. 387 and 399; 1928), gives us a powerful, accurate, and convenient method of exploring molecular spectra, especially in the near and extreme infra-red ...

    Notes: [Auszug] IT is well known from the work of Barkla, Compton, and others that X-rays scattered through 90° by matter are completely polarised, irrespective of whether the electron remains bound or suffers ejection from the atom as the result of the impact of the quantum upon it. The recent discovery of a ...

    Notes: [Auszug] CLERK MAXWELL many years ago surmised that viscous liquids in a state of flow should exhibit birefringence, and devised methods of observing the phenomenon. Vorländer and Walter (Zeits. Phys. Chem., 118, 1; 1925) have recently investigated no fewer than 172 liquids of known chemical composition ...

    Notes: [Auszug] IN a very important paper (Phil. Mag., vol. 33, p. 521 ; 1917), Silberstein developed a theory of molecular refractivity based on the idea that the electric doublets induced by the field of the light wave in the atoms composing the molecule influence each other, the result of such atomic ...

    Notes: [Auszug] IN an earlier note to NATURE (Aug. 25, p. 278) we ventured to suggest that the nebulosity or wings which accompany the original lines of the mercury arc after scattering in benzene liquid, are the effect of those collisions of the incident light-quanta with the molecules which result in a ...

    Notes: [Auszug] As has been emphasised by Prof. Pringsheim in his recent admirable report on the Raman effect (Die Naturwissenschaften, Aug. 3, 1928), there is a far-reaching and fundamental analogy between the behaviour of electrons and of light quanta during their collisions with material particles. The new ...

    Notes: [Auszug] THE thermal agitation of the atoms in solids results, as was shown by Raman (NATURE, Jan. 12, 1922, and Jan. 6, 1923), in a noticeable blue opalescence in the interior of such transparent crystals as quartz or ice when they are traversed by a strong beam of sunlight. In his address on the ...

    Notes: [Auszug] THE presence in the light scattered by fluids, of wave-lengths different from those present in the incident light, is shown very clearly by the accompanying photographs (Fig. 1). In the illustration (1) represents the spectrum of the light from a quartz mercury vapour lamp, from which all ...

    Notes: [Auszug] IN a recent communication on the crystal structure of 1, 3, 5-triphenylbenzene, Dr. Kathleen Lonsdale1 discusses the results of recent X-ray measurements on the crystal and concludes that the planes of the benzene rings of the molecules cannot coincide with the (001) plane of the ...
