The theory of the free radicals of Pauling and Wheland is applied to the electron affinities of the radicals. The results are compared with the measurements of Bent, and they indicate that the charging electron enters in resonance with the whole system of p h ‐electrons. The theory is...
By observing the ratio of the negative ion emission to the electron emission from a thermionic surface of known temperature in an atmosphere of electronegative molecules of known pressure the electron affinity of the atoms can be calculated. A magnetron set up has been used to distinguish...
The Li 2 + molecule has been treated by methods previously applied to the study of Li 2 by the writer. It appears that the dissociation energy of Li 2 + must be greater than that of Li 2 , and is probably 1.30±0.05 e.v. The ratio of one‐ to two‐electron bond strengths appears to be greater...
Hexagonal cyanuric triazide has been examined by means of Laue, rotation and oscillation photographs and by a few spectrometer measurements. The dimensions are a = 8.70A and c = 5.98A. The space group is H 6 3 / m. There are two C 3 N 3 (N 3 ) 3 in the cell. The ten parameters have been...
From rotation and oscillation photographs with Mo K α, rhombic sulphur is found to have the following cell and space group; a = 10.48A, b = 12.92A, c = 24.55A, Z = 128, space group V h 24 ( Fddd ). The structure contains S 8 molecules which are symmetrical puckered rings with S☒S distance...
The reaction of hydrogen and benzene to form 1,2‐dihydrobenzene is considered, and the activation energy of the reaction is calculated with various assumptions concerning directed valence. It is shown that one may calculate approximate heats of reactions by considering exchange integrals only...
Attention is called to the fact that certain important equations of thermodynamics such as the two Gibbs‐Helmholtz equations may be grouped into families, but that a precise definition of such families has hitherto been lacking. For the case of a single phase of k components in equilibrium a...
The tendency of glass forming substances to supercooling is discussed in connection with the existence of large or irregular groups in the melts of such substances. If the size of these groups makes their direct addition to the crystal lattice difficult, and if the forces within them are so...
