Solvent effect on the intensity of CN stretching vibration for some nitriles

The present situation as to tile effect of the medium on electronic and vibrationM spectra is typical of a field which is at t ract ing a rapidly increasing body of interest. In the case of electronic spectra a very promising approach appears to be tha t by KOSOWER (1), who proposed the use of the transition energ'ies corresponding to some appropiate chargetransfer bands as an empirical measure of solvent polari ty; these Iransition energies (designated as Z-values) are linear functions of the Winstein-Griinwald ]2-value,whi('h is a kinetic measure of the ionizing power of the medium. In the case of vibrational spe(.ira, concerned with our present measurements, the theorelieal t reatments up to present proposed (2) are essentially foeuse4 on tile ewduat.ion of ~he extent of electrostatic solute-solvent interactions; tim first equation to be deduced, that by Kirkwood-Bauer-Magat (KBM),

Spectro-Polarization Characteristics of the Sodium Nitrate Polarizer

The polarization characteristics of the sodium nitrate polarization prism are measured. Polarization effect is complete from 350 to 1,000 mµ; and transmission of light uncorrected for reflection at the surfaces is about 90% at above 400 mµ and 37% at 350 mµ. Possibility of making a polarization prism for a wide wavelength range from 250 to 1,000 mµ is discussed.

When eggs of Coccophora Langsdorfii, Fucus evanescens, or Sargassum confusum are treated with zinc chloride solution at a densinty higher than 25per cent, clear blisters are formed over the egg surface. After the morphological polarity was determined, plasmolysis occurs with zinc chloride so that the protoplasm is separated from the cell wall and the blisters appear in the space between the plasm and the cell wall. This indicates that the cell wall has been hardened parallel with the po larity determination. The blisters seem to be composed of the hyaline plasm extruded through small holes of the plasma membrane brought about by treatment with zinc chloride.

On a Sodium Nitrate Polarization Prism and a Polarization Plate of Scattering Type

Two types of polarizers are constructed, one being the “total reflection type” similar to the Feussner prism and the other is the “scattering type”, in which the principle of Christiansen filter holding for the polarization. The former is made of a thin single crystal of sodium nitrate grown between two prisms of SK5 glass or two glass plates which are cemented to two prisms of the same kind of glass by Canada balsam. No use of organic binders to attach the crystal to the glass remarkably simplifies the manufacturing process as well as protection of the polarizers from deteriorations due to the deliquenscence of the crystal. The polarizer of the “scattering type” is constructed by binding directly two roughly ground surfaces of SK5 glass plates with a thin single crystal of sodium nitrate. As SK5 glass has the same refractive index with that of ordinary ray in sodium nitrate, and the orientation of the optical axis of the crystal is so chosen that it lies in the plane of the glass plate, the extraordinary...

The Polarization of Light at Sea

A polarizing prism properly oriented was found to darken the sea relative to the sky, to reduce the brilliance of the sun path and to render the horizon more distinct. In bright weather it increased the visibility of objects against the sea background. Attaching polarizing prisms to a sextant and to binoculars improved these instruments in certain cases. Measurements of the light of the sea ruffled by a breeze from several hundred yards from the observer out to the horizon several miles away showed that the light was often more, and rarely less, than 2/3 polarized with electric vector mainly horizontal but tilted up under certain conditions, e.g., tilted up 30° for the sun bearing 90° and at 45° altitude. From the observations and theory it came out that the sea light was the light of the sky at about 25° to 35° above the horizon reflected by the sea, the reflecting facets of the sea surface being most frequently at about 15° to the horizontal. The width of the sun path calculated from this was in agreement with the observed width of about 6°, 14° and 18° in moderate weather for the sun at altitudes 10°, 20° and 30°, respectively. The explanation is given of a number of breezy sea reflection phenomena.
