Absorption of Ultrasonic Waves in Organic Liquids (II) Liquids with Negative Temperature Coefficient of Sound Absorption (a) Glycols, Cyclohexanol and Cresol
Ultrasonic absorption coefficients (at about 8 Mc/sec) were determined by the pulse technique in glycols, cyclohexanol and m -cresol in dependence of the temperature. Also the ultrasonic velocity (at 1.43 Mc/sec) in these liquids was determined by the ultrasonic interferometry. The experimental absorption coefficient…
Über die thermische Zersetzung von Kaliummanganat(VI)
Abstract Die Darstellung von reinstem K 2 MnO 4 wird beschrieben. Die thermische Zersetzung von K 2 MnO 4 im O 2 ‐ und N 2 ‐Strom im Temperaturbereich 500° bis 900° wird untersucht. Durch quantitative Aufarbeitung des Reaktionsproduktes wird gezeigt, daß diese Zersetzung im Prinzip stets nach der Gl. (3) K 2 MnO 4 = 2…

Vibrational Spectra of Molecules and Complex Ions in Crystals VII. The Raman Spectrum of Crystalline Ammonia and 3-Deutero-Ammonia
The Raman spectra of crystalline NH3 and ND3 were measured at —82°C, using Hg 2536.5A exciting radiation. The fundamentals v1, v2, and v3 were observed, but v4 was not. v2 was split into two components by intermolecular coupling. Lattice frequencies of both translational and rotational origin were observed, and there…
Surface Tension, Density, Viscosity, and Electrical Resistivity of Molten Binary Alkaline‐Earth Borates
Results of an investigation of some properties of the systems CaO‐B 2 O 3 , SrO‐B 2 O 3 , and BaO‐B 2 O 3 are reported. The formation of two liquids at low RO concentrations limited the range of compositions which could be measured. The values of surface tension and temperature coefficient of surface tension obtained…

Electrical and Optical Properties of Intermetallic Compounds. III. Aluminum Antimonide
Measurements of resistivity, Hall coefficient, and optical absorption of AlSb are reported. The width of the forbidden energy band, derived from electrical and optical data, is 1.6 ev at absolute zero. Absorption bands are observed at 0.75 ev in $p$-type samples and at 0.31 ev in tellurium-doped $n$-type specimens. An…
Frequency Dependence of Ultrasonic Cavitation
On the basis of a simplified model an explanation for the high-frequency limit of ultrasonic cavitation is suggested and compared with published experimental data.
The near infra-red absorption spectra of natural and synthetic fibres
The near infra-red region may be used to obtain spectra with polarized radiation of natural and synthetic fibres. This region has considerable experimental advantages and the spectra of poly-L-alanine, polyglycine, wool, silks and commercial regenerated protein fibres are shown and discussed. Besides supplementing oth…
An Electron Interferometer
An interferometer of the amplitude-splitting type has been constructed which operates with electron beams and produces a system of fringes in the viewing instrument. The appearance of the fringes may be varied at will by introducing changes in one of the (electron) optical paths. The instrument utilizes crystalline di…
