Les auteurs présentent une étude systématique des spectres Raman de nombreuses molécules pentatomiques tétraédriques appartenant aux différents groupes de symétrie possibles. Beaucoup n'avaient pas encore été décrits; les autres ont été l'objet d'une étude critique. Les auteurs ont pu ainsi établir un classement plus…
Abstract Bei einer aus vielen starren Fadenelementen bestehenden Molekel wird die statistische (wahrscheinlichkeitselastische) Rückstellkraft sehr gross, sobald die Fadenelemente praktisch vollständig gegeneinander ausgerichtet sind. Es ist daher vorauszusehen, dass bei Einwirkung von Kräften, welche zu einer weitgehe…
The storage field of diaphragms in wave guides is usually described in terms of higher-order evanescent waves. Yet a rectangular wave guide may be thought of as a strip transmission line, which is continuously stub-supported at both edges, and one would not normally describe the storage field of a condenser or coil sh…

Abstract Calculations have been made of the lattice distortion at the free crystal surface of the cube face of alkali halide crystals on the basis of Born's lattice theory, with the result that the displacement of the positive surface ions in a direction perpendicular to the surface differs considerably from that of t…
The factors which determine image contrast in optical and electron micrographs are discussed in relation to a new metal shadow-casting technique whereby the contrast of images is greatly increased by depositing obliquely a thin film of metal on the microscope preparations. Further advantages of the use of shadow-casti…

A review is given of measurements of the thermal conductivity of natural clothing fibres and of formulae that have been proposed for the overall thermal conductivity of fibre-air mixtures in terms of their density and fibre conductivity. Measurements of the conductivity of wool felts ranging in density from 0.01 to 1.…

A new fatigue testing machine capable of making experiments under combined alternating bending and torsion with any phase difference has been devised and proved to be satisfactory in operation by the authors. From the test results obtained by experiments carried out on some metals with the machine, the effect of phase…
