Since to form a hole the size of a molecule in a liquid requires almost the same increase in free energy as to vaporize a molecule, the concentration of vapor above the liquid is a measure of such ``molecular'' holes in the liquid. This provides an explanation of the law of rectilinear diameters...
A study has been made of the products formed when sodium hydroxide and ethyl alcohol react in the absence of water. Evidence has been found which indicates a reaction in which sodium ethylate and water are produced. Three types of tests have been made to determine the amount of water formed. The...
In §§1–5 data on the decomposition of azomethane are presented and compared with those obtained by Ramsperger, with which they do not entirely agree. In §6 the possible effect of self‐heating of the reacting gas is considered. In §7 some modifications in the theory of unimolecular...
An apparatus for measuring the rates of gaseous reactions in the presence of large excesses of inert gases, using an adaptation of the Huygens manometer as the pressure measuring device, is described.
Further experiments with greatly improved conditions show that the liquid crystal swarms or groups of molecules at 125°C give an x‐ray diffraction intensity distribution curve which is similar to but not exactly like that of the transparent liquid at 150°C. The former has a greater intensity...
The exact classical kinetic energy for a system of point masses is obtained. From this the correct form for the quantum‐mechanical Hamiltonian operator is derived. If the assumption of small vibrations is applied to this operator, the familiar approximation of a rigid top plus normal coordinate...
I. The method given by Eidinoff and Aston for calculating the limiting high temperature rotational partition function has been further simplified. An important special case, comprising molecules which may be represented by a rigid framework to which symmetrical tops are attached in any position...
