Role of Nitric Oxide in the Thermal Decomposition of Nitrous Oxide

F. Kaufman、Norman J. Gerri、Roger E. Bowman1956-07-01The Journal of Chemical Physics

The rates of decomposition of N2O and of formation of NO were measured simultaneously in a static system. NO yields at the beginning of reaction are as high as 50 to 60%, but NO quickly inhibits its own further formation. From initial NO yields, information about the reaction of oxygen atoms with N2O and about wall re…

The structure of sodium dithionite and the nature of the dithionite ion

Jack D. Dunitz1956-07-01Acta Crystallographica

The structure of sodium dithionite has been determined by X-ray analysis. The crystals are monoclinic, a----6"404:k0.0045, b----6-559~:0.0028, c----6"586:k0-0056 /~, fl---119 31':k0 02 ', space group P2/c, with two molecules of Na2S204 in the unit cell. The structure was refined by successive difference Fourier projec…

γ-Ray Initiated Polymerization of Crystalline Monomers1

A. J. Restaino、Robert B. Mesrobian、Herbert Morawetz 等 6 位作者1956-07-01Journal of the American Chemical Society

Acrylamide, methacrylamide, methylene-bis-acrylamide, vinyl carbazole, vinyl stearate, acrylic acid, methacrylic acid and potassium, calcium and barium acrylates have been polymerized in the solid state by irradiation with γ-rays. Further, the molecular weight of polyacrylamide obtained at low conversion was constant…

Transient Nuclear Induction and Double Nuclear Resonance in Solids

B. Herzog、E. L. Hahn1956-07-01Physical Review

The behavior of transient nuclear induction signals from solids is described by a stochastic model based on a Markoff process. The model assumes the presence of local dipolar field fluctuations in a crystal due to a set $B$ of coupled nuclei. These fluctuations can destroy or enhance the observed precessional coherenc…

On the scatttering of waves by an infinite grating

V. Twersky1956-07-01IRE Transactions on Antennas and Propagation

Using Green's function methods, we express the field of a grating of cylinders excited by a plane wave as certain sets of plane waves: a transmitted set, a reflected set, and essentially the sum of the two "inside" the grating. The transmitted set is given by\psi_{o} + 2\SigmaC_{\upsilon}G(\theta_{\upsilon}, \theta_{o…
