Because of the chemical inertness of the paraffin hydrocarbons and of the closely related cycZoparaffins, no satisfactory crystalline derivatives can be prepared. Reliance is therefore placed upon the physical properties (boding point, density, and refractive index) of the redistilled samples. These are collected together in Table III,6. 

The low reactivity of aliphatic ethers renders the problem of the preparation of suitable crystalline derivatives a somewhat difficult one. Increased importance is therefore attached to the physical properties (boding point, density and refractive index) as a means for providing preliminary information. There are, however, two reactions based upon the cleavage of the ethers which are useful for characterisation. 

Esteis are often characterized by their physical properties. These include boding point, freezing point, melting point, density, refractive index, residue or ash... 

V indicates the principal value) are applied to a function F = F + F" (Bode, 1950 Smith, 1985 Hopfe et al., 1981). Such so-called dispersion relations exist between the (real) refractive index and the absorption index. Dedicated software programs are available, also specially for (infrared) spectroscopic purposes (Hopfe, 1989), a generalization for oblique incidence on layered systems was given by Grosse and Offermann (1991). 

JT-Ray powder photographs of the oxyfluoride have been indexed on the basis of a cubic unit cell, a = 10 032 0 002 k, U = 1010 A, /) = 4-20 (by CCI4 displacement), Z = Dc = 4-48. The powder photograph shows a close resemblance to that of nitrosyl hexafluoro-osmate(v), NOOsF, a = 10-12 k, Z = 8, U = 1038 A, which has been prepared recently in this laboratory. Both patterns closely resemble that of potassium hexafluoro-antimonate(v), KSbF, a = 10-15, Z = 8, (/ = 1046 A, the structure of which has been described by Bode and Voss. ... 

Of course several formulations are possible for the compound. Fortuntely the solid gave a simple X-ray powder diffraction photograph which was indexed on the basis of a cubic unit cell, a = 10.032A. The compound was apparently structurally similar to potassium hexafluoro-antimonate (V) the structure of which had been given by Bode and Voss Furthermore we found that nitro-syl hexafluoro-osmate (V) and nitrosyl hexafluoro-anti-monate (V) were also isomorphous with the compound. Figure 4 shows the close resemblance of the X-ray powder... 

The development presented here for the complex impedance, Z = Zr+ jZj, is general and can be applied, for example, to the complex refractive index, the complex viscosity, and the complex permittivity. The derivation for a general transfer function G follows that presented by Nussenzveig. The development for the subsequent analysis in terms of impedance follows the approach presented by Bode. ...

Semmler and Bode have shown that santalol is a primary alcohol (or alcohols), hy its oxidation to santal aldehyde. According to these chemists this aldehyde hods at 152 to 155 at 10 mm., has a specific gravity 0-995 at 20, refractive index 1-51066, and is dextro-rotary. Its semicarhazone melts at 230. ...
