A Test for Electron Transfer in the Intermetallic Compound, V4Al23

Description: Abstract: "Abnormally short interatomic distances are characteristic of aluminum-transition element compounds which occur at the aluminum-rich ends of the phase diagram." Summary: "The theoretical model assumed in this investigation was that of spherical distribution of electrons centered about atomic sites in the V4Al23 structure, represented by the theoretical scattering factors for the isolated atoms. ...It is evident from the (Fo-Fc)-synthesis maps that too much scattering power has been … more

The Mass Spectrum of Stannane

Description: From abstract: "The mass spectrum of stannane, SnH4, has been studied. Ion fragmentation patterns for both the singly and doubly charged fragments were obtained employing 70-volt electrons. From appearance potential data, an estimation of the bond energies of the tin-hydrogen bond in the ion-species SnH+3-H, SnH+2-H, SnH+-H, Sn+-H has been made along with [delta]Hf for SnH4. The studies were first made with tin of normal isotopic abundance, and then the results were corroborated with SnH4 prepa… more
